Bernie, whose mass is 70 kg, leaves a ski jump with a velocity of 21 m/s. What is Bernie's momentum as he leaves the ski jump?
Answer: Bernie's momentum as he leaves the ski jump 1,470 kg m/s.
Explanation:
Mass of the Bernie's body = 70 kg
Velocity with which Bernie left for the ski jump = 21 m/s
Momentum of the Bernie :
\(Momentum=Mass\times Velocity=70 kg\times 21/ms=1,470 kg m/s\)
Bernie's momentum as he leaves the ski jump 1,470 kg m/s.
