Problem 14.92 The roller coaster car has a speed of vA 26 ft/s when it is at the crest of a vertical parabolic track. The total weight of the car and the passengers is 360 lb. Neglect friction and the mass of the wheels. (Figure 1) Figure 1 of 1 x y 200 (40000-) 200 ft 200 ft Part A Determine the car's velocity when it reaches point B. Express your answer to three significant figures and include the appropriate...

A The length of the roller coaster track is 100 ft and the elevation change of the track from point A, at the bottom of the track, to point B, at the top of the track is 20 ft. The roller coaster car, including the passengers, weights 1,200 lb, and the force of friction between the car and the tracks is 20 lb. The speed at point A is 45 ft/s. Determine the speed at point B. B Solve the...

The roller coaster car has a mass of 850 kg including its passenger. It is released from rest at the top of the hill A Neglect friction, the mass of the wheels, and the size of the car. Take h_B = 19 m, rho_B = 9.5 m. h_C = 12 m and rho_c = 6 m. Part A Determine the minimum height h of the hill crest so that the car travels around both inside the loops without leaving the...

A roller-coaster car has a mass of 1040 kg when fully loaded with passengers. As the car passes over the top of a circular hall of radius 18 m, its speed is not changing. (a) At the top of the hill, what is the normal force (using the negative for the downward direction) on the car from the track if the car's speed is v = 7.4 m/s? (b) What is if v = 17 m/s? Use g = 9.81...

A roller-coaster car (mass = 988 kg including passengers) is about to roll down a track. The diameter of the circular loop is 21.5 m and the car starts out from rest 36.2 m above the lowest point of the track. Ignore friction and air resistance. X is the how high the car is= 36.2 m Y is the diameter of the loop= 21.5 m. What is the force exerted on the car by the track at the top of...

A car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...
