Question

Bobsleds racing down a bobsled run often suffer glancing collisions

with the vertical walls enclosing the run. Suppose that a

bobsled of 600 kg traveling at 120 km h approaches a wall at

an angle of 3.0 and bounces off at the same angle. Subsequent

inspection of the wall shows that the side of the bobsled made

a scratch mark of length 2.5 m along the wall. From these

data, calculate the time interval the bobsled was in contact

with the wall, and calculate the average magnitude of the force

that acted on the side of the bobsled during the collision.
