A ball of mass 150 g moving with an acceleration of 20m//s^(2) is hit by a force, which acts on it for 0.1 s. What is the impulsive force?

A ball of mass 150 g moving with an acceleration of 20m//s^(2) is hit

1.	A ball of mass 150 g moving with an acceleration of 20m//s^(2) is hit by a force, which acts on it for 0.1 s. What is the impulsive force?
Answer» 0.1N 0.5N 0.3N 1.2N Solution :Force = MASS `XX` acceleration and Impulse `(J)= Fxxt= mxxa xx t` `therefore J= 150xx10^(-3) xx 20 xx 0.1=300 xx 10^(-3)= 0.3N`
