A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding a rock. The total mass of the wagon, rider, and rock is 93.9 kg. The mass of the rock is 0.279 kg. Initially the wagon is rolling forward at a speed of 0.469 m/s. Then the person throws the rock with a speed of 15.8 m/s. Both speeds are relative to the ground. Find the speed of the wagon after the rock is thrown (a) directly forward in one case and (b) directly backward in another.

A man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.480 m/s. The total mass of the sled, man, and rock is 93.5 kg. The mass of the rock is 0.320 kg and the man can throw it with a speed of 16.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in...

A 68.5-kg person throws a 0.0430-kg snowball forward with a ground speed of 32.0 m/s. A second person, with a mass of 58.0 kg, catches the snowball. Both people are on skates. The first person is initially moving forward with a speed of 2.15 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. (Take the direction the snowball...

1. The person in Fig. 1 weighs 90 kg and the mass of the wagon (excluding the rocks) is 100 kg. Initially there are 50 one-kg rocks in the wagon. At t 0 the person starts to throw rocks out the back of the wagon at the rate of 1 rock per second. If the rocks leave the person's hand at a speed of 30 m/s, plot the position, X, and velocity U, of the wagon for t-1 to 50...
