A wheel has a constant angular acceleration of 15.3 rad/s2. The wheel was initially moving at 31 rad/s. How many revolutions did the wheel make during the f = 4.7 s)? Please round your answer to one decimal place.A solid rigid body whose moment of inertia is 2.6 I'Lg-n'r2 spins about an axis of rotation that goes through its center of mass. The constant angular speed of the rigid body is 24 radr's. What is its rotational kinetic energy in Joules]? Please round your answer to the nearest whole number {integer}
