Awagon 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 93.5 kg. the mass of the rock is 0.310 kg. initially the wagon is rolling forward at a speed of 0.540 m/s. then the person throws the rock with a speed of 16.5 m/s. both speeds are relative to the ground. find the speed of the wagon after the rock is thrown directly forward.
