Question

According to Newton s second law of motion `F =ma` where `F` is the force required to produce an acceleration a in a body of mass m If a = 0 then `F = 0` no external force is required to move a body uniformly along a straight line If a force `F` acts on a body for t seconds the effect of the force is given by Impulse =F `xx` t =change in linear momentum of the body
Average force exerted by the bat is .
A. `480N`
B. `120N`
C. `1200N`
D. `840N`

Answer 1

Correct Answer - a
As Impulse `=F xx t`
`:. F = ("Impulse")/(t) = 4.80N` .
