A) If the puck was initially at rest, find the x component of its final momentum.
B) Find the y component of its final momentum

✔ 最佳答案
A)Along the x-direction:
F = (mv - mu) / t
0.340 = (mv - 0) / 4.50
The x-component of the final momentum, mv = 0.340 × 4.50 kg•m/s = 1.53 kg•m/s
B)
Along the y-direction:
F = (mv - mu) / t
0.240 = (mv - 0) / 4.50
The y-component of the final momentum, mv = 0.240 × 4.50 kg•m/s = 1.08 kg•m/s
