Hi there!
Recall that:

Given an electric field, the potential difference can be solved by using integration. Similarly:

We can differentiate the electric potential equation to solve for the electric field.
Use the power rule:

Differentiate the given equation.

Or:

- Initial velocity=20m/s
- Final velocity=0m/s(As the car stops)
- Acceleration=-8m/s^2
- Distance=s=26m
We need to verify the thrid equation of kinematics here





The squirrel has a good luck ,Car gets stopped just 1m away from the squirrel .
Answer:
Explanation:
<h2><u>Given</u> :-</h2>
<h2><u>To Find</u> :-</h2>
<h2><u>Formula to be used</u> :-</h2>
Where,
- K.E. = Kinetic energy possessed by the body
- M = Mass of the body
- V = Velocity of the body
<h2><u>Solution</u> :-</h2>








- Velocity of the vehicle at the instant is

So, there should be two forces acting on the refrigerator: the applied force and the friction force.
The question mentioned that the friction force was set to zero, so the only effective force now would be the applied force.
We have an applied force of 400 N to the right, this means that:
<span>The magnitude of the net force is 400, directed to the right.</span>
Answer:

Explanation:
Mass of the Sun, 
The radius of the Sun, 
We need to find the acceleration due to gravity on the surface of the Sun. It is given by the formula as follows :

So, the value of acceleration due to gravity on the Sun is
.
