Question

A ball is projected from the ground level in vertically
upward direction with an initial velocity u. The ball goes
up to a maximum height H and then starts moving
downward. Finally the ball falls back on the ground. It is

given that motion of the ball under the action of gravity
alone and effect of air resistance, if any, is negligible
a. What is the value of maximum height H up to which
the ball goes
b. What time does the ball take to reach the highest
point during its motion?
c. After what time does the ball falls back on the
ground
d. Draw position-time graph for entire motion of the
ball. What is the slope of the graph?
e. Draw speed-time and velocity-time graph for the
entire motion of the ball.

Answer 1
