To assess whether your calculations are reasonable, we'll analyze a similar situation to the one described in the problem introduction. suppose the same sled is released from the same height on the same slope. this time, however, assume that the coefficient of kinetic friction between the ground and the sled is a known quantity, μ, and, as before, constant throughout the trip. after the sled is released, it slides the same distance d1 down the slope and then moves a certain (unknown) distance along the horizontal terrain before stopping. find the distance d traveled by the sled from the end of the slope until it comes to a stop. express your answer in terms of the variables d1, μ, and θ.
