Answer:

The concept to solve this problem is related to the relativistic physics for which the speed of the object in different frames of reference is related. This concept is called Velocity-addition formula

and can be written as,

Where,

u = Velocity of a body within a Lorentz Frame

v = Velocity of a second frame

u'= The transformed velocity of the body within the second frame

c = speed of light

Replacing we have to

Therefore the meteor moving with respect to the Earth to 230'700.000m/s

**Answer:**

The acceleration is 2.448 meters per square second and is vertically upward.

**Explanation:**

The Free Body Diagram of the plastic ball in the liquid is presented in the image attached below. By Second Newton's Law, we know that forces acting on the plastic ball is:

**(1)**

Where:

- Buoyant force, measured in newtons.

- Mass of the plastic ball, measured in kilograms.

- Gravitational acceleration, measured in meters per square second.

- Net acceleration, measured in meters per square second.

If we know that , and , then the net acceleration of the plastic ball is:

The acceleration is 2.448 meters per square second and is vertically upward.

The motion of **sand **is due to the movement of **conveyor belt**. The **horizontal **distance between the end of the **conveyor **belt and the middle of the **collecting **drum is 2.044 meters.

The equation of **motion **is the relation between the **distance**, velocity, acceleration and time of a moving body.

The **second **equation of the motion for **distance **can be given as,

Here, is the **initial **body, is the **acceleration **of the body due to gravity and is the time taken by it.

Given information-

The **conveyor **is tilted at an angle of **18**° above the horizontal.

The Sand is moved without slipping at the rate of **2** m/s.

The sand is collected in a big drum **5** m below the end of the conveyor belt.

The **horizontal **component of the velocity is given as,

The **vertical **component of the velocity is given as,

Put the value in the above **equation **as,

The horizontal distance between the end of the **conveyor belt **and the middle of the **collecting drum **is,

Thus, the **horizontal **distance between the end of the **conveyor **belt and the middle of the **collecting **drum is 2.044 meters.

Learn more about the **equation **of **motion **here;

**Answer:**

x = 2.044 m

**Explanation:**

given data

initial vertical component of velocity = Vy = 2sin18

initial horizontal component of velocity = Vx = 2cos18

distance from the ground yo = 5m

ground distance y = 0

from equation of motion

solving for t

t = 1.075 sec

for horizontal motion

x = 2cos18*1.075

x = 2.044 m

**Answer:**

We know also that the formula to find the power is given by,

**Answer:**

315.5 N/m

**Explanation:**

m = 500 g = 0.5 kg

T = 0.25 second

Total energy, E = 4 J

Let K be the spring constant.

The formula for the time period is given by

K = 315.5 N/m

**Answer:**

r = 7.1 × 10⁻¹⁵

**Explanation:**

**(a) 328.6 kg m/s**

The linear impulse experienced by the passenger in the car is equal to the change in momentum of the passenger:

where

m = 62.0 kg is the mass of the passenger

is the change in velocity of the car (and the passenger), which is

So, the linear impulse experienced by the passenger is

**(b) 404.7 N**

The linear impulse experienced by the passenger is also equal to the product between the average force and the time interval:

where in this case

is the linear impulse

is the time during which the force is applied

Solving the equation for F, we find the magnitude of the average force experienced by the passenger:
