Ezra (m = 20.0 kg) has a tire swing and wants to swing as high as possible. he thinks that his best option is to run as fast as he can and jump onto the tire at full speed. the tire has a mass of 10.0 kg and hangs 3.50 m straight down from a tree branch. ezra stands back 10.0 m and accelerates to a speed of 3.62 m/s before jumping onto the tire swing. (a) how fast are ezra and the tire moving immediately after he jumps onto the swing? m/s (b) how high does the tire travel above its initial height?
