Academics

Q1. Horse races once around a circular track in a time of 176 s, with a speed of 26 m/s. What is the radius of the track?

Q2. A 55 kg swimmer is standing on a stationary 175 kg floating raft. The swimmer then runs off the raft horizontally with a velocity of +3.7 m/s relative to the shore. Find recoil velocity that the raft would have if there were no friction and resistance because of the water.
