A block of mass M-1.2 kg is attached to a string which is wrapped around a pulley. As the block accelerates due to gravity the pulley rotates clockwise. The pulley can be thought of as a thin cylinder of mass m = 0.5 kg and radius r=0.24 m. Consider positive to be the block moving down and the pulley rotating clockwise. What is the downwards acceleration of the block? m/s² an What is the angular acceleration of the pulley? rad/s² Starting from rest, how long does it take the block to hit the floor, 1.42 m below? d= t= 8- S Through how many radians did the pulley turn at this point? M rev rad How many revolutions did the pulley make? If the mass of the block were decreased, the acceleration would Select an answer If the mass of the pulley were increased, the acceleration would Select an answer If the radius of the pulley were increased the acceleration would Select an answer If the solid cylindrical pulley were replaced by a hoop of equal mass and radius, the acceleration would Select an answer
