7. [-/1 Points] ASK YOUR TEACHER PRACTICE ANOTHER During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot him. The cannon ball has a mass of 51.0 kg and its horizontal component of velocity is 10.00 m/s when the 65.0 kg performer catches it. If the performer is on nearly frictionless roller skates, what is his recoil velocity in meters per second? Reading 8. [-/1 Points] DETAILS Additional Materials + m/s Reading OSCOLPHYS2016 8.5.P.043.

[-/1 Points] DETAILS OSCOLPHYS2016 8.7.P.055. Calculate the increase in velocity (in m/s) of a 4040 kg space probe that expels 3200 kg of its mass at an exhaust velocity of 4.00 x 10³ m/s. You may assume the gravitational force negligible at the probe's location. m/s MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER
