Question 1

A cinder block of mass m = 4.0 kg is hung from a nylon string that is wrapped around a frictionless pulley having the shape of a cylindrical shell, as shown in the figure. If the cinder block accelerates downward at 4.90 m/s2 when it is released, what is the mass M of the pulley?



◦ 6.0 kg
◦ 8.0 kg
◦ 10 kg
◦ 4.0 kg
◦ 2.0 kg

Question 2

A uniform rod is 2.0 m long. It is hinged to a wall at its left end, and held in a horizontal position at its right end by a vertical very light string, as shown in the figure. What is the angular acceleration of the rod at the moment after the string is released if there is no friction in the hinge?



◦ 7.4 rad/s2
◦ 11 rad/s2
◦ 3.3 rad/s2
◦ 15 rad/s2
◦ It cannot be calculated without knowing the mass of the rod.
