A 91 kg janitor wearing running shoes is running across an ice rink at a
speed of 3.2 m/s. They try to stop abruptly, but keep sliding across the
surface of the ice. The ice exerts a frictional force of 13.4 N to slow them
down. How far do they travel before halting to a stop?

- Ken and Barbie are skating together on a rink at 3.00 m/s. Ken keeps asking Barbie how much she weights. Annoyed, Barbie pushes away from Ken so that she speeds up to 4.0 m/s and he slows down to 2.25 m/s in the same direction. Assuming that the friction is negligible, if Ken's mass is 70 kg, what is Barbie's mass?arrow_forwardYesterday, I was roller skating. I was moving with a speed of 5.0 m/s on a road.
