Do you mean in general or in a piece of paper?
Kinetic, potential because, at the top of the ramp it’s going faster. Potential at the bottom of the ramp is potential because, it’s not doing any motion.
Newton's second law states that F=ma so that means force =mass×acceleration force and mass
Overloading
Explanation:
The reason reason why the mcb of rupa's room keeps tripping is due to the fact that excessive current has being supplied to his room.
MCB stands for a miniature circuit breaker.
A miniature circuit breaker opens up the electrical circuit by switching it off when there is overloading or faulty connections.
- A MCB helps to control the flow of current and it is designed to hand certain limits of electrical voltage.
- If the MCB keeps tripping, it suggests a surge in current supplied, overloading or probably a faulty connection.

For an object`s motion, the Kinematic equation is,
Here, v is the final velocity and h is stands for the height of the object and a is the acceleration of the object.
As according to question,
and 
Thus, putting these values in above equation, we get
or
Therefore, initial velocity is 2.8 m/s
