Question

pls answer this question
this belongs work power energy

Answer 1

Answer:

Explanation: kinetic energy at B may be zero

Because at ground position value of final velocity is zero show kinetic energy is zero

Answer 2

Answer:

As energy is conserved energy , at any point Energy of body is sum of total energy .

In this case body have kinetic energy and potential energy.

1)At maximum height it has maximum potential energy and Zero kinetic energy

2)At lowest height or at extreme point it has maximum kinetic energy and zero potential energy.

So according to the diagram the body is at maximum point it has only kinetic energy but it has same magnitude as of Potential energy which is =mgh
