- A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has an 8.00-m radius, at how many revolutions per minute are the riders subjected to a centripetal acceleration equal to that of gravity?3. A rocket was launched with a speed v = 150 m/s and an acceleration of 425 m/s² at an angle a = 80°, determine the rocket's rate of increase in speed and its normal acceleration. Also, determine the radius of curvature of its path.When an object is in uniform circular motion, the velocity of the object never changes. True False
