4.5 Question Warm-up 1. Josh and Liam create a device to launch a 1.2 kg Chemistry textbook into space. (well the air anyways) It starts with a mechanical spinner that will spin the textbook around until reaching a speed of 45 m/s. The box will then travel up a 9.0 m ramp with an incline of 40 to the horizontal as shown in the system diagram and fly into the air. If there is a coefficient of friction of 0.30 between the ramp and the textbook, determine the maximum height the textbook will reach. (YOU HAVE TO USE ENERGIES TO SOLVE EXCEPT FRICTION) 40
