Answer: 32kgm/s
Explanation:
Given that,
impulse I = ?
Mass of baseball M = 0.140 kg
force F = 100 N
Time = 0.32 seconds
Recall that impulse of an object is the product of force and the time during which it acts, and impulse is also equal to change in momentum.
i.e Impulse = Force x Time
Also, Change in momentum = Force x Time
So, I = Ft = m(Vf - Vi)
hence, Change in momentum = Ft
Momentum = 100N x 0.32 seconds
Momentum = 32kgm/s
Thus, the change in momentum of the baseball is 32kgm/s
