A 78.5kg ice hockey goalie, originally at rest, catches a 0.120kg hockey puck slapped at him at a velocity of 36 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction it came.

a) What would the final velocity of the puck be in this case? Be careful with the sign!

b) What would the final velocity of the goalie be in this case?

Expert Solution

the answers are,

(a) the finla velocity of puck be - 35.88 m/s

( b) the final velocity of thr goalie be 0.109 m/s.

Two identical pucks collide elastically on an air hockey table. Puck 1 was originally at rest; puck 2 has an incoming speed of 7.96 m/s and scatters at an angle of 30° with respect to its incoming direction. What is the velocity (magnitude in m/s and direction in degrees counterclockwise from the +x-axis) of puck 1 after the collision? (Assume the +x-axis is to the right.) Magnitude: Direction:

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 hockey puck B rests on frictionless, level ice and is struck by a second puck...

A hockey puck B rests on frictionless, level ice and is struck by a second puck A, which was originally traveling at 40.0 m/s and which is deflected 30.0° from its original direction. (See the Figure). Puck B acquires a velocity at a 45.0° angle to the original direction of A. The pucks have the same mass. (a) Compute the speed of each puck after the collision. (b) What fraction of the original kinetic energy of puck A dissipates during...

Hockey puck B rests on a smooth ice surface and is struck by a second puck A, which has the same mass. Puck A is initially traveling at 16.0m/s and is deflected 22.0 degrees from its initial direction. Assume that the collision is perfectly elastic. a) Find the final speed of puck b after the collision. b) Find the final speed of puck a after the collision. c) Find the direction of b's velocity after the collision

Suppose a hockey player sees a puck sliding on level ice (neglect friction on the puck)...

Suppose a hockey player sees a puck sliding on level ice (neglect friction on the puck) to the left. The player decides to gently push the puck up the ice (so perpendicular to the puck's initial velocity), and continues to push the puck in the same direction for 10 seconds. Afterward, the puck just continues to slide across the ice without the player nearby. Select ALL that are true. A. The puck's speed stays the same after 10 seconds for...

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...
