A sledder effortlessly glides from position A across the snow to position B (as shown in the diagram at the right). Resistance forces are negligible. At position B, the kinetic energy of the sledder is Joules and the total mechanical energy is Joules. In moving from position A to position B, the sledder lost J of potential energy and gained J of kinetic energy.

An object of mass m starts from the left with velocity v0 and travels along a track moving right from position 1 to position 5 as shown. The track is completely frictionless, except for a horizontal region of length Δxf, where the coefficient of kinetic friction between the track and the object is μk. The object finally collides with a spring with a spring constant k and comes to rest in position 5 , compressing the formerly relaxed spring by a maximum amount, Δx. Which statements about the mechanical energy of the object-earth-spring system as the object moves from position 1 to position 5 is FALSE? Assume that the center of mass of the block is at the exact same vertical heights as positions 1, 3, and 5 . Note that while the object is moving at positions 1 through 4, the magnitudes of the velocity vectors shown may not be to scale. Note that more than more than one statement might be false (unlike what you will see on the final exam, where you will only be able to select a single response). The potential energy is the same at positions 1, 3 , and 5 . The gravitational potential energy is the same at positions 1, 3, and 5 . The total mechanical energy is the same at positions 1, 2, 3, 4, and 5. The kinetic energy is the same at positions 1 and 3 . The total mechanical energy is the same at positions 4 and 5 . The total mechanical energy is the same at positions 1, 2 , and 3.
