initial velocity=0m/s
acceleration=4.2m/s^2
time taken =5s
then final velocity
v=u+at
or, v=0+4.2*5
so final velocity is 21m/s
Answer:
15.68 m/s
Explanation:
Given that,
She catches the ball 3.2 s later at the same height from which it was thrown.
When it reaches the maximum height, its height is equal to 0.
It will move under the action of gravity.
2 here comes for the time of ascent and descent.
So,
So, the initial upward speed of the ball is 15.68 m/s.
