11) A basketball of mass half kg is released from the height of 78.4 m and falls freely to theground. Calculatea) time taken by the ball to reach the ground.velocity of the ball on the reaching the ground.c) the height of the ball at half the time it takes to reach the ground.RE
Answers
Answer:
A ball is projected from the ground level in vertically upward direction with an initial velocity u. The hall 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, 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 shape of the graph?
(e) Draw speed-time and velocity-time graph for entire motion of the ball.
