An object with mass M is sliding along a horizontal, frictionless surface with a velocity of V. It then slides up a hill that is 15 degrees above the horizontal. The object travels a distance D parallel to the surface of the hill before coming to rest.
If the hill does have friction, what is the work down by friction. Give your answer in terms of M, V, D, g, and Constants.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
