mp 2. A person of mass m, slides down a playground slide of length / with friction. The slide makes an angle of 30 degrees with the horizontal. (Note: If you are stuck, review the components of gravitational forces on a ramp.) (a) The person moves with constant velocity. In terms of the given quantities and any fundamental constants, derive an equation for the coefficient of kinetic friction, (b) Suppose the slide has a different so that the person accelerates while sliding down the slide. Derive an equation for the acceleration of the person, , in terms of , any of the other given quantities above, and fundamental constants as needed.
