A hockey stick exerts an average force of 39N on a 0.2kg hockey puck over a displacement of 0.22m. if the hockey puck started from rest, what is the final velocity of the puck? Assume no friction.

Your physics teacher walking with the aid of a cane approaches a skateboard of 3.5 kg lying on the side walk. Pushing with an angle of 60 degree down from the horizontal with his cane, he applies a force of 115N, which is enough to toll the skateboard out of his way. Calculate the initial acceleration

A solo arctic adventurer pulls a string of two toboggans of supplies across level, snowy ground. The toboggans have masses of 95kg and 55kg. Appling a force of 165N causes the toboggans to accelerate at 0.61m/s2. Find the tension in the rope attached to the second toboggan.

A 75kg man is standing on a scale in an elevator when the elevator begins to descend with an acceleration of0.66 m/s2. What is the reading on the scale while elevator is accelerating?

A 32 kg baby is practising climbing skills on a climbing wall, while being belayed by her parent. The child loses her grip and dangles from the rope. When the parent starts lowing the child, the tension in the rope is 253N. Find the acceleration of the child when she is first being lowered.

The lighter person on an Atwood machine is 45kg. If the tension in the rope is 512N, what is the mass of the second person? What is the acceleration of the two people?

    1. Tension, Weight, Friction: You are taking advantage of an early snow to go sledding. After a long afternoon of going up and down hills with your sled, you decide it is time to go home. You are thankful that you can pull your sled without climbing any more hills. As you are walking home, dragging the sled behind you by a rope fastened to the front of the sled, you wonder what the coefficient of friction of the snow on the sled is. You estimate that you are pulling on the rope with a 2 pound force, that the sled weighs 10 pounds, and that the rope makes an angle of 25 degrees to the level ground…
