Answer:

Impulse of watermelon = -48 kg-m/s

Step-by-step explanation:

Given:

Final momentum of water melon = 2 kg-m/s

Initial momentum of water melon = 50 kg-m/s

Find:

Impulse of watermelon

Computation:

Impulse = Δp

Impulse = Final momentum - Initial momentum

Impulse of watermelon = Final momentum of water melon - Initial momentum of water melon

Impulse of watermelon = 2 - 50

Impulse of watermelon = -48 kg-m/s
