Unformatted text preview: Solution: The height of the car initially is: h = 6.0 sin 15 = 1.55 m The gravitational potential energy at the top is: PE = mgh = 27400 J At the bottom of the ramp, all of the energy is converted to kinetic energy and energy (heat) lost to due to friction. The energy lost due to friction is: W friction = Fd = 9000 J Thus, the kinetic energy remaining is: KE = PE - W friction = 18400 J The final velocity is: m KE v 2 = = 4.52 m/s...
