Question

11. A rocket is projected vertically upward. In the above problem the mean velocity of rocket in reaching the maximum height will be?​

Answer 1

Answer:

Maximum height is achieved when velocity becomes zero. Thus from this graph we can conclude that maximum distance is achieved at t=110 s.

Maximum height = Area under the curve from t=0 to t=110, which is given as
