An opposing player charging the net runs into the goalie for your ice hockey team, and the goalie lays motionless on the ice. When you get to him, he is conscious and alert but complaining of not being able to move. He denies having any pain and is becoming very anxious and scared. He has no difficulty breathing. You complete your initial evaluation and find all vitals to be within normal limits, but the athlete does not respond to painful...

Q1) Two identical pucks collide on an air hockey table. One puck was originally at rest. If the incoming puck has a speed of 6.50 m/s and scatters to an angle of 30.0º,what is the speed of the second puck after the collision? (You may use the result that θ1−θ2=90º for elastic collisions of objects that have identical masses.) Q2)A block of mass m = 3.0 kg, moving on a frictionless surface with a speed 2.9 m/s makes a perfectly...

A 45.0-kg girl is standing on a 152-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat, frictionless surface. The girl begins to walk along the plank at a constant velocity of 1.55 m/s to the right relative to the plank. (Let the direction the girl is moving in be positive. Indicate the direction with the sign of your answer.) (a) What is her velocity relative to the surface of ice?...
