Aball is hurled straight up at a speed of 15 m/s, leaving the hand of the thrower 2.00 m above the ground. compute the times and the ball’s speeds when it passes an observer sitting at a window in line with the throw 10.0 m above the point of release.

5.37 m/s

0.98 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

Velocity of the ball when it passes an observer sitting at a window is 5.37 m/s

Time taken by the ball to pass the observer sitting at a window is 0.98 seconds
