[2] A rollercoaster of mass m = 950 kg in an amusement park is about to take on avertical loop of radius R = 15 m. Upon reaching the top of the loop (wheneverybody is the upside-down), it is found that the normal force exerted on thetrack on the rollercoaster is downward and half the magnitude as its total weight.Ignore all the frictions.(a) What is the speed v of the roller coaster upon reaching the top of the loop?(b) What is the speed vo of the rollercoaster as it passes the bottom of the loop?(c) Find the normal force n exerted on the rollercoaster by the track as it passesthrough the midpoint on its way up.

Given: The mass of roller coaster,m=950 kg Radius of vertical loop,R=15 m
