Water-Jetpack that you'll design needs to lift a 100kg person. It will have two jets (as seen in the picture) with 5cm nozzle diameter each. a. Is a frame of reference put on earth an inertial one or not? How do we treat it in mechanical engineering, why? b. Find out the water velocity coming out of each nozzle for keeping the person steady on the air (no acceleration) and for c. Accelerating the person vertically in the air with 3m/s NOTE: i) Assume that the water speed at the inlet from sea is so low that it can be neglected. ii) List all the assumptions you made clearly.
