Physics A Sample Exam 4 07/26/18 A Physics A student throws a 1350 gram cantaloupe off a 15.0m high platform. The initial speed of the cantaloupe is 12.0m/s. Final answers must be to the correct number of significant figures (g-9.8066m/s). a. What is the initial kinetic energy of the cantaloupe (6pts)? 3. 97.2 2.1 What is the initial potential energy of the cantaloupe (6pts)? b. pe , 1.350 Kg、 16' 9-8 : 198/ 198.4 What is the total initial energy of the cantaloupe (6pts)? c. 2961 1. 350 (12) What is the speed of the cantaloupe in m/s just when it hits the ground below? You can only use energy considerations to solve this problem (7pts) d. 20.9m/s
