Question

If an object is dropped from 10 m above the ground, what is the height at which it’s kinetic energy and potential energy are equal?

Step 1

Given that the object is dropped from a height of 10m above the ground.

The question is to find at what height kinetic energy and potential energy of the object are equal.

Let that height be h_{1}.

At height “h_{1}” kinetic energy of the object and potential energy of the object are equal.

Step 2

When the object is at h1,

KE = PE

Step 3

We can find V from law of conservation of energy ,

Decrease in PE is equal to increa...
