Question

At the maximum height of a body which is thrown vertically up
(a) velocity is not zero but acceleration is zero.
(b) acceleration is not zero but velocity is zero
(c)both acceleration and velocity are zero.
(d)both acceleration and velocity are not zero.​

Answer 1

Answer:

At the maximum height of a body which is thrown vertically up

Correct option:

(b) Acceleration is not zero but velocity is zero.

Explanation:

If body is going in opposite direction of gravity. Gravity will continuously keep it attracting towards the earth until it reaches infinity distance.

Answer 2

Answer:

The correct option is (b).

Explanation:

an object is thrown vertically upwards then as it reaches its highest point its velocity decreases and at some point it gradually turns to zero. Whereas it's interesting to know that at at it's highest point acceleration of the ball remains 9.8 m/s2
