2. A 55 kg human is shot out the end of a cannon with a speed of 18 m/s at an angle of 60. Ignore friction and solve this problem with energy conservation. As he exits the cannon, find: a. horizontal and vertical components of his velocity b. kinetic energy Find at the top of the trajectory: c. the horizontal and vertical components of his velocity d. his kinetic energy e. his potential energy relative to the exit of the cannon f. his maximum height 18 m/s Ground level S PO UNIT 5 ENERGY: WS 9 Review Problems - Forces, Work, & Energy 1. A 10,000 kg bus is traveling on the road below. The speed of the bus at point A is 26.82 m/s. The engine has been disengaged and the bus is coasting. Friction and air resistance are assumed negligible. Height values are above sea level. a) Find the speed of the bus at point B. b) An extortionist has planted a bomb on the bus. If the speed of the bus falls below 22.35 m/s (50 mph) the bomb will explode. Will the speed of the bus fall below this value and explode? If you feel the bus will explode, identify the interval in which this occurs. 65 m physics Info 60 m 55 m 50 m A B C D 65 m E 60 m F 55 m 50 m
