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.

What if? if the temperature near the cliff suddenly falls to 0°c, reducing the speed of sound to 331 m/s, what would the initial speed of the rock have to be (in m/s) for the soccer player to hear the sound of the splash 2.90 s after kicking the rock?
