Question

A football player kicks a 0.8 kg ball and imparts it a velocity 12 ms-1 .the contact between the foot and ball is only for one -sixtieth of a second. Find the average kicking force.

Answer 1

f=a*s
v to power 2=u to power 2 + 2as
and v=u+at
v=0+12/16
v=3/4m/s
9/16=0+2*12*s
9/16=24*s
s=9/(16*24)
f=9/(16*24)*12
=9/32N

Answer 2

I hope the answer is correct....:)
