Rank in decreasing order the distances traveled by objects having the following pairs of average velocity and time of motion. I. vavg = +2.0 m/s, t = 2.0 s
II. vavg = +3.0 m/s, t = 2.0 s
III. vavg = -3.0 m/s, t = 3.0 s

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 1.5m/s, and the rope pulls up on the sled at a 32 ∘ angle. you estimate that the mass of the sled, with your friend on it, is 65 kg and that you're pulling with a force of 80 n .
