A volleyball is spiked so that its incoming velocity of $+4.0 m / s$ is changed to an outgoing velocity of $-21 m / s$. The mass of the volleyball is $0.35 kg$.
What impulse does the player apply to the ball?
$$
[-8.75 kg \cdot m / s ]
$$

A volleyball is spiked so that its incoming velocity of +4.0𝑚/𝑠 is changed to an outgoing velocity of −21𝑚/𝑠. The mass m of the volleyball is 0.35𝑘𝑔.
What impulse I does the player apply to the ball? [−8.75𝑘𝑔⋅𝑚/𝑠]
Impulse I = m*ΔV = 0,35*(-21-4) = -8,75 kg*mps
