Document Summary
Open book, closed notes, do not write on this sheet. Problem 1 (20 points): a child having a mass of 30. 0 kg jumps downward onto a trampoline at a speed of 4. 0 m/s. Problem 2 (35 points): a bowler rolls a 16. 0-lbm ball at a single stationary pin having a mass of 3. 0 lbm. Problem 3 (45 points): two small spheres a and b, weighing 5 lb and 2 lb, respectively, are connected by a rigid rod of negligible weight. The two spheres are resting on a horizontal, frictionless surface when b is suddenly given the velocity v0 = (10. 5 ft/s)i. Determine the linear momentum of the system and its angular momentum about its mass center g. (answers: l = 0. 6522 lb-s, h = 0. 2717 ft-lb-s)
