Question

If a body is projected vertically up, its velocity decreases to half of its initial velocity at a
height 'h' above the ground. Then maximum height reached by it is
1) 3h
2) 4h
3) 2h
4) 4h/3
​

Answer 1

Answer:

When an object launches in the vertically upward direction, then the velocity of the object keeps on decreasing due to the opposition of gravity. Therefore, at the maximum height, the velocity of the object becomes zero.

Answer 2

Answer:
