A solid sphere is rolling smoothly with a speed of V, = 14.7 m/s on a horizontal surfac en rolls up a ramp to a height of h and continues to move with a speed of Vy = 5.3 m/s. What is the value of the heis le moment of inertia of a solid sphere is I = 0.40 mR. Please round your answer to one decimal place.The propeller of an airplane was rotating at an initial angular speed of 9.4/ rad/s when the pilot increased the speed at a constant angular acceleration. 8.9 seconds later, the propeller is observed to be rotating at 51.5x rad/s. Through how many revolutions has the propeller rotated through during the 8.9 seconds time? Please round your answer to two decimal places
