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 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...

Chapter 07, Problem 60 Go 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 99.1 kg. The mass of the rock is 0.329 kg. Initially the wagon is rolling forward at a speed of 0.504 m/s. Then the person throws the rock with a speed of 16.1 m/s. Both speeds are relative to the ground. Find the speed...

A person is standing on and facing the front of a stationary skateboard while holding a construction brick. The mass of the person is 54.0 kg, the mass of the skateboard is 4.10 kg, and the mass of the brick is 2.50 kg. If the person throws the brick forward (in the direction they are facing) with a speed of 15.0 m/s relative to the skateboard and we ignore friction, determine the recoil speed of the person and the skateboard....

A rock is thrown horizontally from the top of a 10 m cliff with an initial horizontal velocity of 10 m/s. It has a Kinetic energy of 78 J when it in at a height of 3.0 m above the ground. If 20% of its initial mechanical energy is used in against the air friction, the mass of the rock is: 0.5 kg 1.0 kg 1.5 kg 2.0 kg None of...
