A 73.0 Kg hockey player glides across the ice on skates with steel blades by applying force 400.0 N. Find final velocity of scatter and distance travelled by him after 5.0 s. Estimate coefficient of kinetic friction between ice and steel blades? If the mass of player reduces to half, what is new coefficient of kinetic friction? What are possible ways to reduce kinetic friction in this case?

In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 1.97 m/s. However, this speed is inadequate to compensate for the kinetic friction between the puck and the ice. As a result, the puck travels only one-half the distance between the players before sliding to a halt. What minimum initial speed should the puck have been given so that it reached the teammate, assuming that the same force of kinetic friction acted...

7. A 77.0 kg ice hockey goalie, originally at rest, catches a 0.150 kg hockey puck slapped at him at a velocity of 34.0 m/s. Suppose the goalie and the ice puck have an elastic collision and the puck is reflected back in the direction from which it came. What would their final velocities (in m/s) be in this case? (Assume the original direction of the ice puck toward the goalie is in the positive direction. Indicate the direction with...

1`A puck of mass 0.110 kg slides across ice in the positive x-direction with a kinetic friction coefficient between the ice and puck of 0.167. If the puck is moving at an initial speed of 15.0 m/s, find the following. (a) What is the force of kinetic friction? (Indicate the direction with the sign of your answer.)

a 90 kg mini car moves at 10 m/s across fairly smooth ice on a frozen lake toward a rock with a mass of 6 kg. when thrown it becomes lodged in the mini car. How fast would the rock need to be moving to stop the mini cars approach on impact? Include a useful sketch of the pre/post situation. If the rock is  thrown with a velocity of 200 m/s, what is the total kinetic energy of the mini car/rock...
