A 0.12-kg apple falls off a tree branch that is 2.3 m above the thick grass. The apple sinks 0.067 m into the grass while stopping. Determine the average contact force that the grass alone exerts on the apple while stopping it. Ignore air resistance.

If a 0.12-kg apple falls off a tree branch that is 2.3 m above the thick grass. The apple sinks 0.067 m into the grass while **stopping**, then the **average **contact **force **that grass would exert on the apple would be 1.177 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of **momentum**.

As given in the problem if a 0.12-kg apple **falls **off a tree branch that is 2.3 m above the thick grass. The apple sinks 0.067 m into the grass while **stopping**,

The contact **force **on the apple = 0.12 × 9.81

if the temperature of star b is twice the temperature of star a, what can we say about the energy emitted by the surface of star b compared to the energy emitted by star a?

The **blackbody radiation** **energy **emitted by star a is **1/16 factor** of star b energy.

We need to know about **black body radiation** to solve this problem. The energy radiated by a black body object is proportional to the area and the fourth power of temperature. It can be determined as

P = A . e . σ . T⁴

where P is power, A is surface area, e is emissivity, σ is Stefan Boltzmann's constant ( 5.67 x 10¯⁸ W/m²K⁴) and T is temperature.

From the question above, we know that

Tb = 2 Ta

By using the **black body radiation** formula, the ratio of temperature is

Ta⁴ / Tb⁴ = Pa / Pb

Ta⁴ / Tb⁴ = Ea / Eb

Hence,

Ta⁴ / Tb⁴ = Ea / Eb

Ta⁴ / (2Ta)⁴ = Ea / Eb

Ta⁴ / 16Ta⁴ = Ea / Eb

1/16 . Eb = Ea

Thus, the energy of star a will have 1/16 factor of star b energy

Exercise 9: The brass plate of an outdoor sculpture experiences shear forces in an earthquake. The plate is 0.8m ^ 2 and 0.5 cm thick. What is the force exerted on each of its edges if the resulting displacement x is 0.16 mm? (Shear modulus = 3.5 * 10 ^ 10 * Pa ) .

Its edges are subjected to a **force** of 2.8 x 1010 N at the specified **shear** **stress** and area.

The **force** known as shear stress is the tendency for a material to deform by slippage along a plane or planes parallel to the applied stress. **Shear** **stress** or pressures, as their name suggests, tend to "shear" objects or produce material deformation.

The formula for shear stress is given as:

F = Aτ

where;

F is the **force** applied, A is the area of the surface, and τ is the **shear** **stress**

We have,

**Shear** **modulus**, τ = 3.5 × 10¹⁰ Pa

The **area** of the plate is A = 0.8 m²

Then,

F = ( 0.8 m² ) × (3.5 × 10¹⁰ Pa)

F = 2.8 x 10¹⁰ N

As a result, as the **shear** **stress** grows, so does the force applied to each of its edges that causes the specified displacement.

A **tiger **leaps **horizontally **from a 5.5 m rock with a **speed **of 3.6 m/s. So the tiger will land 2.772 m **away **from the base.

In **mechanics**, acceleration refers to how quickly an object's velocity alters in relation to time. The **vectorized **magnitude of accelerations. An object's **acceleration **is determined by the **direction **of the net force pushing against it.

**Acceleration **has a direction and a magnitude, making it a vector quantity. A vector quantity is a **velocity **as well. **Acceleration **is defined as the change in the vector of velocity over a period of time divided by the **duration **of the change.

According to the question, the given values are,

For **y component **:

Acceleration, a = -9.8 m/s²

Velocity, v₀= 0 m/s

Δy = -5.5 m

For **x component** :

a = 0 m/s²

v₀ = 3.6 m/s

Δy = v₀t + 1/2 at²

**Explanation:**

The cat in this question is stationary. As a result, the acceleration of this cat will be zero. By Newton's Second Law of Motion, the net force on this cat will also be zero.

If the floor is level, there will be two forces acting on this cat:

The weight of the cat, which points downwards.The support force (normal force) of the floor on the cat, which points upwards.For the net force to be zero, these two forces need to balance each other. For that, they need to have the same magnitude and point in opposite directions. Therefore, the magnitude of the support force (normal force) will be equal to the magnitude of the weight of this cat.

**Explanation:**

A ball is equipped with a speedometer and launched straight upward. The speedometer reading three seconds after launch is shown at the right; the ball is moving upward. At what approximate times would the ball be moving downward and display the following speedometer readings?

The time shown by the speedometer corresponding to speed of **10 m/s** is** 1 s.**

The time shown by the speedometer corresponding to speed of** 20 m/s **is** 1 s.**

The time shown by the speedometer corresponding to speed of **30 m/s **is **1 s.**

1. As shown by the speedometer on the right.

The speed of** 10 m/s** indicated by the **speedometer** to the right may be used to calculate how long the ball has been falling from the maximum altitude it reached.

Equation for** free fall**: Vf = Vo - gt

Vo=0, Vf=gt, and t=Vf/g

I suggest using an a**pproximation **of g for this problem: g = 10 m/s2 (I'll explain why in a moment).

1 second is equal to [10 m/s]/[10 m/s2].

The time is now** dropping**. From it has been four seconds since launch, the upward time was three seconds. You may use this to determine the launching speed.

2. The moment the speedometer registers 20 m/s

Determine the **launching speed** first:

**Vo - gt = Vf**

Given that the ball took 3 seconds to ascend and that its speed was zero at its highest point, you may calculate:

0 = Vo - gt

Vo=gt=10 m/s2 3 s = 30 m/s

Now, while the ball is** moving upward **and the speedometer reads 20 m/s, use the beginning** velocity **to compute.

t = [30 m/s - 20 m/s] / [10 m/s2] = 1 s 20 m/s = 30 m/s - 10 m/s2

Therefore, t = 1 s is the** initial **solution.

3. The moment the speedometer registers 30 m/s.

The **projected speed** for the launch is also 30 m/s.

This reading therefore reflects the precise moment the ball was **released**.

**Time** is therefore 0 and the launch moment remains the same.
