012 10.0 points A ball with mass 0.365 kg and speed 8.3 m/s rolls across a level table into an open box with mass 0.535 kg. The box with the ball inside it then slides across the table for a distance of 0.33 m. The acclerating gravity is 9.81 m/s. What is the coefficient of kinetic friction of the table? 013 (part 1 of 2) 10.0 points After being struck by a bowling ball, a 1.8 kg bowling pin sliding to the right at 4.3 m/s collides head-on with another 1.8 kg bowling pin initially at rest. Find the final velocity of the second pin in the following situations: a) The first pin moves to the right after the collision at 0.6 m/s. Answer in units of m/s. 014 (part 2 of 2) 10.0 points b) The first pin stops moving when it hits the second pin. Answer in units of m/s.015 10.0 points A uniform 210 g rod with length 55 cm rotates in a horizontal plane about a fixed, vertical frictionless pin through its center. Two small21 g beads are mounted on the rod such that they are able to slide without friction along its length. Initially the beads are held by catches at positions 12 cm on each sides of the center, at which time the system rotates at an angular speed of 12 rad/s. Suddenly, the catches are released and the small beads slide outward along the rod. Find the angular speed of the system at the instant the beads reach the ends of the rod. Answer in units of rad/s.016 10.0 points A student holds two lead weights, each of mass 5.1 kg. When the students' arms are extended horizontally, the lead weights are 1 m from the axis of rotation and the student rotates with an angular speed of 2.1 rad/sec. The moment of inertia of student plus stool is 7.2 kgm- and is assumed to be constant; i.e., the student's arms are massless! Then the student pulls the lead weights horizontally to a radius 0.28 m from the axis of rotation. 0 00 (a) (b) Calculate the final angular speed of the system. Answer in units of rad/s
