A4.00-m long rod is hinged at one end. the rod is initially held in the horizontal position, and then released as the free end is allowed to fall. what is the angular acceleration as it is released? (the moment of inertia of a rod about one end is ml2/3.)

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem
