Answer 1

Answer:

What was said by the colonel after he said that they were within the hydraulic press ?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.
