1. Kim places a 5.0 kg physics cat on top of the 3.0 kg physics textbook, which is placed upon the 1.0 kg physics balance scale, which is on the physics table. (a) Draw a force diagram for the physics textbook. (b) Determine the force exerted by the table on the scale. (c) Determine the force measured by the scale, and the reading on the scale. (Answers: 88 N, 78 N, 8.0 kg) 2. After having just missed qualifying for the luge for the 2014 Winter Olympics, Charlie continues his training by sliding down a frictionless ramp with an incline of 40. (a) Draw a force diagram for Charlie and his sled (total mass: 80 kg), including an acceleration vector and an appropriate frame of reference. (b) Write scalar equations for Fnetx and Fnety. (c) What is his acceleration? (d) If Charlie and his sled were placed on a scale tilted at the same angle as the incline, what would be the normal force on him and the sled, and what would the scale read (in kg)? (Answers: 6.3 m/s2, 6.0x102 N, 61 kg)
