An amusement park builds a ride in which the victim is made to spin about a pole with a rocket strapped on his seat. The rider, box and rocket have an initial total mass of 170 kg. Neglect the mass of the rod of length 6 m .What is the moment of inertia of rider, box and rocket about the pole? The acceleration of gravity is 9.8 m/s^2 . Treat the rider, box and rocket as a point mass. Answer in units of kg · m^2
B) The rocket develops a thrust of 98 N perpendicular to the path of the rider. What is the initial angular acceleration of the rider? Answer in units of rad/s^2
C)After what time t is the rider’s velocity equal to 5 m/s? Neglect the change in mass of the rocket. Answer in units of s.
D)Gas exits the rocket at vt = 390 m/s. What mass per second must leave to develop the thrust F given above? Answer in units of kg/s .
