Question
A player throws a ball upwards with an initial speed of 29.4 m s-1.
To what height does the ball rise and after how long does the ball return to the player’s hands ?
(Take g = 9.8 m s-2and neglect air resistance).
Solution
Initial velocity of the ball, u = 29.4 m/s
At maximum height, the velocity of the ball becomes zero.
Final velocity of the ball, v = 0
Acceleration, a = – g = – 9.8 m/s2
Using third equation of motion,
Height to which the ball rises is given by,
