A boy sleds down a hill and onto a frictionless ice - covered lake at 14.9 m/s. In the middle of the lake is a 1,000 kg boulder. When the sled crashes into the boulder, he is propelled over the boulder and continues sliding over the ice at 14.9 m/s. If the boy's mass is 40.0 kg and the sled's mass is 13.0 kg, what are the speeds (in m/s) of the sled and the boulder after the elastic collision?

A 57.0-g tennis ball is traveling straight at a player at 21.0 m/s. The player volleys the ball straight back at 25.0 m/s. If the ball remains in contact with the racket for 0.060 s, what average force acts on the ball? (a) 22.6 N (b) 32.5 N (c) 43.7 N (d) 72.1 N (e) 102 N
A boy sleds down a hill and onto a frictionless ice-covered lake at 11.7 m/s. In the middle of the lake is a 1,000 kg boulder. When the sled crashes into the boulder, he is propelled over the boulder and continues sliding over the ice at 11.7 m/s. If the boy's mass is 40.0 kg and the sled's mass is 20.0 kg, what are the speeds (in m/s) of the sled and the boulder after the elastic collision?

A loaded gun is dropped on a frozen lake. The gun fires, with the bullet going horizontally in one direction and the gun sliding on the ice in the other direction. The bullet's mass is 0.04 kg, and its speed is 320 m/s. If the gun's mass is 2.2 kg, what is its speed (in m/s)?
Ken and Barbie are skating together on a rink at 3.00 m/s. Ken keeps asking Barbie how much she weights. Annoyed, Barbie pushes away from Ken so that she speeds up to 4.0 m/s and he slows down to 2.25 m/s in the same direction. Assuming that the friction is negligible, if Ken's mass is 70 kg, what is Barbie's mass?

A 747 jetliner lands and begins to slow to a stop as it moves along the runway. If its mass is 3.56×105 kgkg , its speed is 25.5 m/sm/s , and the net braking force is 4.30×105N4.30×105N, what is its speed 8.07 s later?
A 2.50 kg box sits halfway up a 16.0 m long ramp that is inclined at an angle of 16.00. You shove a second box, of mass 1.50 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 20.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.200. Where, from the bottom of the ramp, do they come to rest?
