A hockey puck slides along the ice when it collides with a filled water bottle which was sitting at rest on the ice. The velocity of the puck just before colliding with the water bottle is (58 – 6j) m/s and the velocity of the puck just after the collision is 5 m/s at 36.87° counterclockwise from -x. The mass of the puck is 0.2 kg and the mass of the water bottle is three times as large. a. What is the velocity of the water bottle immediately after the collision? Write answer in component vector form.

1. A hockey puck slides along the ice when it collides with a filled
water bottle which was sitting at rest on the ice. The velocity of the
puck just before colliding with the water bottle is (58 – 6j) m/s
and the velocity of the puck just after the collision is 5 m/s at
36.87° counterclockwise from -x. The mass of the puck is 0.2 kg
and the mass of the water bottle is three times as large.
