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 onlyfor one sixtieth ofa second find the average kicking force |

Answer» SOLUTION :Given: Mass of the ball = 0.8 kg Final velocity `(V) = 12 ms^(-1)`and time`t = 1/60 s ` Initial velocity = 0 We know the average kicking force ` F = ma = (m(v-u))/(t) = (0.8(12-0))/((1/60))` ` F = 576 N` |
