The zacchini family was renowned for their human- cannonball act in which a family member was shot from a cannon using either elastic bands or compressed air. in one version of the act, emanuel zacchini was shot over three ferris wheels to land in a net at the same height as the open end of the cannon and at a range of 69 m. he was propelled inside the barrel for 5.2 m and launched at an angle of 53°. if his mass was 85 kg and he underwent constant acceleration inside the barrel, what was the magnitude of the force propelling him? (hint: treat the launch as though it were along a ramp at 53°. neglect air drag.)
