Problem 1 700) kg В 90 m 20 m 50 m A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A, rolls with negligible friction down the incline and follows the track around the loop of radius 20 m. Point B, the highest point in the loop, is at a height of 50 m above the lowest point on the track. Indicate on the figure the point P at which the maximum speed of the car is attained. (a) i. ii. Calculate the value vmax of this maximum speed. V 2-2g(90-0) -26-9.(0) Vee S17u Ve- L1 (b) Calculate the speed vB of the car at point B.
