Consider the child standing on the top of a tower of height h, shown in figure-l .12. He throws the ball up and the ball follows the trajectory as shown in figure. Draw the displacement versus time graph of the ball's motion during its flight. Take vertically upwards direction as positive x-axis.

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity time graph of the ball during its flight ( air resistance is neglected).

A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its height if the air resistance is not ingnored ?

A ball travelling in positive X direction with speed V0 hits a wall perpendicularly and rebounds with speed V_(0) . During the short interaction time (Delta t) the force applied by the wall on the ball varies as shown in figure. Draw the velocity-time graph for the ball during the interval 0 to Deltat

A person standing on the roof of a building throws a ball vertically upward at an instant t = 0 . The ball leaves his hand with an upward speed 20 m/s and it is then in free fall. The ball rises to a certain height and then moves down. On its way down, the ball just misses to hit the roof of the building and keeps falling towards the earth. the ball hits earth at t = 5 sec. considering that (i) the vertically upward direction is the positive Y-direction (ii) the position of ball at t = 0 is the origin (iii) the ball does not rebound and comes to rest at the same place where it hits earth and (iv) air resistance is negligible. (Take g = 10 m//s^(2) ) Position -time graph for the given motion of the ball is :
