Question

The Zacchini family was renowned for their humancannonball 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 68 m. He was propelled inside the barrel for 5.7 m and launched at an angle of 50°. If his mass was 81 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 50°. Neglect air drag.)

Explanation / Answer

It depends on the method use. If you push something up a ramp there are 2 vertical forces:
- the upwards vertical component of the applied force
- the downwards weight.
These have to be added to get the total vertical force.

But here is how I'd do it.

Step 1. Find the velocity, v, he must leave the cannon.

You could work this out from basics or use the range formula:
R = v
