A 0.111 kg hockey puck moving at 55 m/s is caught by a 80 kg goalie at rest. With what speed does the goalie slide on the (frict
Andrews [41]

Answer: 0.076 m/s

Explanation:

Momentum is conserved:

m v = (m + M) V

(0.111 kg) (55 m/s) = (0.111 kg + 80. kg) V

V = 0.076 m/s

After catching the puck, the goalie slides at 0.076 m/s.

iVinArrow [24]

Answer: 0.17hp

Explanation:

Power output = power input × 85%

Power output = power input × 0.85

Power input = IV/0.85

Power input = 9×12/0.85

Power input = 108/0.85

= 127.058 watts

Converting to horse power = 127.058W × 1horse power/745.7W

= 127.058 × 0.001341

= 0.17hp
