17. 

A hockey puck is traveling to the left with a velocity of v1 = 10 m/s when it is struck by a hockey stick and given a velocity of v2 = 20 m/s as shown. Determine the magnitude of the net impulse exerted by the hockey stick on the puck. The puck has a mass of 0.2 kg.

[A]. Imp = 6.00 N-s
[B]. Imp = 2.00 N-s
[C]. Imp = 2.78 N-s
[D]. Imp = 5.68 N-s

Answer: Option D
