Q1. A luge and its rider, with a total mass of 83kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 44m/s. Assume that they stop with the constant deceleration of 2.9 m/s2.
Q2. A large wheel is coupled to a wheel with half the diameter. How does the rotational speed of the smaller wheel compare with that of larger wheel? How do the tangential speeds at the rims compare (assuming the belt doesn't slip)?
