Box on a ramp 4.0 m A box slides along a horizontal surface (position A), and then encounters a ramp. The box slides up the ramp (position B) to the top, and then slides some more along a second horizontal surface (position C). Use g = 10.0 m/s2 for this problem. a Part (a) o Homework I Unanswered I Due Oct24th, 11:59 PM The box has a mass of2.00 kg, and the box's speed when it is at the bottom ofthe ramp is 15.0 m/s. If there is no friction between the box and the ramp, calculate the kinetic energy of the box when it reaches the top ofthe ramp.
