A 5.0n force is applied to a 3.0kg ball to change its velocity from +9.”m/s to +3.0 m/s. The impulse on the ball is _I think it’s -18

Given,

The force is F=5 N.

The mass is m=3.0 kg

The velocities are 9 m/s to 3 m/s

The impulse is:


\begin{gathered} I=m(v_f-v_i) \\ \Rightarrow I=3(9-3) \\ \Rightarrow I=(18kgm)/(s) \end{gathered}

The answer is 18 kgm/s
