Part (a) Assuming negligible friction, determine the speed of the riders at the bottom of its arc, given the system's center of mass travels in an arc having a radius of 12.8 meter and the riders are near the center of mass in m/s.
r = 12.8 meter
m = 59 kilogram
Part (b) Find the centripetal acceleration at the bottom of the arc in m/s2?
Part (c) Determine how many times her weight is the normal force exerted by the ride on a 59 kilogram rider?
