Answer:
Initial velocity of the ball final velocity =0m/s
acceleration due to gravity (g)=−10m/s 2 (upward motion)
By using the formula,
v=u+at
O=25+(−10)×t
10t=25
t=2.5sec.
The time taken for upward journey is equal to the time taken for downward journey.
Therefore, total time taken by the ball =2.5+2.5=5sec.
