Problem 2. A bobsleigh 4-man crew accelerates their vehicle to V0=5 m/s before jumping into it and sliding down the racetrack. The total mass of the vehicle and crew is m=630 kg. The runners are made of steel and the kinetic friction coefficient between steel and snow is 0.05. The length of the racetrack is L=1,300m and its vertical drop from start to end is H=115m. a) Ignoring friction and air resistance, what would be the final speed of the bobsleigh at the bottom of the racetrack in m/s, km/h, mph? Does this result depend on the shape of the racetrack? b) Ignoring air resistance but accounting for friction, what would be the final speed of the bobsleigh at the bottom of the racetrack in m/s, km/h, mph? Assume a straight linear racetrack.
