Answer 1

Hii friend

Here is your answer follows...

Given,

velocity= 20m/s
distance= 25m.

To find:-

T=?

Formula:-

Velocity= distance/time
time= distance/velocity

Calculation:-

distance of reaching the ball

v²-u²=2as

v²=2as

s= 20×20/2×10

S=20m
time= 25/20

time= 1.25 secs.

Hope this helps you a little!!!
