A playground ride consists of a disk of mass M = 43 kg and radius R = 2.4 m mounted on a low-friction axle. A child of mass m = 16 kg runs at speed v = 2.7 m/s on a line tangential to the disk and jumps onto the outer edge of the disk. Consider the system consisting of the child and the disk, but not including the axle. Which one of the following statements is FALSE, for the time interval from just before to just after the collision? (Measure torque about the middle of the disk.) Do you know how do I measure the torque about the middle of the disk?
