A hockey puck (mass = 1 kg) leaves the players stick with a speed of 30 m/s and slides on the ice for 100 meters before coming to rest. What is the friction coefficient between the puck and the ice?

60.A 60.0-kg skier with an initial speed of 12.0 m/s coasts up a 2.50-m high rise as shown. Find her final speed at the top, given that the coefficient of friction between her skis and the snow is 0.80. K₁ 35° V₁ = ? 2.5 m

A car traveling at 22 m/s runs out of gas while traveling up a 200 slope. How far up the hill will it coast before starting to roll back down? Assume that car rolls without friction.

An arrow hits a tree penetrating 10 cm as it is brought to rest from its initial speed of 50 m/s inside the tree. The arrows mass was 50 g. a) what average force did the tree exert on the arrow to bring it to rest? 

A boy slips off a spherical ice mound of radius 7.  At what height above the ground does the boy lose contact with the ice?  Assume the ice is frictionless.

You are driving your car on a straight road with a coefficient of friction between the tires and the road of 0.55. A large piece of debris falls in front of your view and you immediate slam on the brakes, leaving a skid mark of 30.5 m (100-feet) long before coming to a stop. A policeman sees your car stopped on the road, looks at the skid mark, and gives you a ticket for traveling over the 13.4 m/s (30 mph) speedlimit. Draw the FBD of the car with complete details.

Denisse is playing a pinball machine. she notices that the 0.012 kg ball is shot from the plunger and moves into a circular path with a radius of 0.22 m. if the magnitude of the force necessary to keep the ball in the Circular path is 0.030 N, what is the speed of the steel ball?

A 86.0 kg diver steps off a 10.0 m high diving board and drops, from rest, straight down into the water. If he comes to rest 7.20 m beneath the surface of the water, determine the average resistive force exerted by the water.

= = The coefficient of friction between the block of mass m₁ 3.00 kg and the surface in the figure below is μK: rest. What is the speed of the ball of mass m2 = 5.00 kg when it has fallen a distance h = 1.70 m? m/s m₁ m₂ 0.445. The system starts from

Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?
