A football is kicked into the air vertically upwards. What is its

a) acceleration

b) velocity at the highest point

Answers (1)

a) when the football is kicked into the air, the only force working on it is the gravitational force. Hence the acceleration will be caused due to this force which will be in the downward direction towards the centre of the Earth.

b) when the ball is thrown upward, no horizontal forces act on it and hence the horizontal component velocity becomes nil. The vertical component of velocity at the highest point is V_{y}=0. Hence, the net velocity when the ball reaches the highest point is also zero.
