2. The diagram below shows a 10,000 kg bus traveling on a straight road which rises and falls. The speed of the bus at point A is 27 m/s (60 mph). The engine has been disengaged and the bus is coasting. Friction and air resistance are assumed negligible. The numbers on the right show the altitude above sea level in meters. The letters A-F correspond to points on the road at these altitudes. 65 m 65 m E 60 m 60 m D. F 55 m 55 m 50 m 50 m C. B.

a Find the potential energy, kinetic energy, and mechanical energy at point A
b. Find the potential energy, kinetic energy, and mechanical energy at point B. Calculate the speed of the
bus at this point too.
Does the bus make it to the top of the hi ? li yes, what is the speed of the bus at the top of the hill? If
no, how high above sea level does the bus make it before starting to roll backward?
