- In the winter sport of bobsledding, athletes push their sled along a horizontal ice surface and then hop on the sled as it starts to careen down the steeply sloped track. In one event, the sled reaches a top speed of 9.2 m/sm/s before starting down the initial part of the track, which is sloped downward at an angle of 9.0 ∘∘.arrow_forwardA skier starts at rest atop a ski slope that has a slope of exactly 37.0∘.37.0∘.
