The car of roller coaster in the following figure has a mass of 650 kg, including its passengers. If the car starts from the point A with a speed v4= 5 m/s, determine the minimum height h of the hill crest so that the car travels around the inside loop without leaving the track. Neglect friction, the mass of the wheels, and the size of the car. Take the radius of curvature of B loop pB as 8 m and the acceleration due to gravity g as 9.81 m/s. В h 16 m
