It’s a snowy day and you’re pulling a friend along a level road
on a sled. you’ve both been taking physics, so she asks what you
think the coefficient of friction between the sled and the snow is.
you’ve been walking at a steady 1.5 m/s, and the rope pulls up on
the sled at a 30° angle. you estimate that the mass of the sled, with
your friend on it, is 60 kg and that you’re pulling with a force of
75 n. what answer will you give?

A12-g wad of sticky clay is hurled horizontally at a 100-g wooden block initially at rest on a horizontal surface. the clay sticks to the block. after impact, the block slides 7.5 m before coming to rest. if the coefficient of friction between the block and the surface is 0.65, what was the speed of the clay immediately before the impact?
