Question

Hockey, which slides at a speed of 3.5 m/s, is hit in the sliding direction. During the stroke, the racket applies a force of 32 N to the puck for 0.17 seconds. At what speed does the puck move after the stroke? The weight of the disc is 150 g.

Favourite answer

impulse: FΔt = mΔv

32N * 0.17s = 0.150kg * Δv → → Δv = 36 m/s

final v = 3.5m/s + 36 m/s = 40 m/s

to two significant digits.
