A wagon is rolling forward on level ground. Friction is negligible.The person sitting in the wagon is holding a rock. The total massof the wagon, rider, and rock is 95.5 kg. The mass of the rock is0.290 kg. Initially the wagon is rolling forward at a speed of0.470 m/s. Then the person throws the rock with a speed of 16.5m/s. Both speeds are relative to the ground. Find the speed of thewagon after the rock is thrown directly forward.
m/s

A 40.0 kg girl gets on her 10.0 kg wagon on level ground withtwo 5.0 kg bricks. She throws the bricks horizontally off the backof the wagon one at a time at a speed of 7.0 m/s relative toherself.

a) How fast does she go after throwing the second brick?

b) How fast would she go if she threw both bricks at the sametime at 7.0 m/s relative to herself?

A girl of mass 56.0 kg stands on the edge of africtionlessmerry-go-round of mass 825
kg and radius 3.72 m that is not moving. She throws a 1.13 kgrockin a horizontal
direction that is tangent to the outer edge of themerry-go-round.The speed
of the rock, relative to the ground, is 7.28 m/s. Assume thatthemerry-go-round is a
uniform disk. Calculate:
(a) the angular speed (magnitude of angular velocity) ofthemerry-go-round (Hint:
assume conservation of angular momentum) and
(b) the linear speed (magnitude of the tangential velocity) ofthegirl after the rock
is thrown.


A 67.0 kg person throws a 0.0410 kg snowball forward with a ground speed of 29.0 m/s. A second person, with a mass of 60.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.50 m/s, and the second person is initially at rest. What are the velocities of the two people after the snowball is exchanged? Disregard the friction between the skates and the ice
