Initially the wagon is rolling forward at a speed

Reference no: EM13655733

A wagon is rolling forward on level ground. Friction is negligible. The person sitting in the wagon is holding arock. The total mass of the wagon, rider, and rock is 98.0kg. The mass of the rock is 0.300kg. Initially the wagon is rolling forward at a speed of 0.500 kg m/s. Then theperson throws a rock at a speed of 16.0 m/s. Both speeds arerelative to the ground. Find the speed of the wagon after the rockis thrown directly forward in one case and directly backward in another.
