Question

A roller coaster car of mass 800 kg when released from rest at point A (height h above the ground) slides along the track and inside the loop of radius 16.0 m. The car never loses contact with the track.

A) Draw below a free body diagram for the car the car at the top of the loop.

B) If the normal force acting on the car at the top is 1500 N, what is the speed of the car at the top of the loop?

C) if the car was released at a height 55 m and the speed at the top of the loop is 17 m/s, what is the amount of thermal energy produced by friction from the point of release to the top of the loop?

Loop the Loop Figure 1)A roller coaster car may be approximated by a block of mass m. The car, which starts from rest, is released at a height h above the ground and slides along a frictionless track. The car encounters a loop of radius R as shown. Assume that the initial height h is great enough so that the car never loses contact with the track. Figure 1 of 1 위부

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...

? A roller coaster car has a mass of 800 kg. It is launched horizontally from a giant spring (spring constant 35 kN/m), rolls 10m and then goes through a vertical loop-the-loop track of radius 7 m. On average, for every meter the car rolls on the track, thermal energy increases by 800 J. The designer, who wants to go home for the weekend, says that compressing the spring 3 m should give the car enough energy to safely go...

PLEASE SHOW WORK! A roller coaster starts from rest at a height h at the left side of a loop-the-loop, as shown in the figure. It is not attached to the track in anyway, and there is no friction from the track or from air resistance. If the radius of the loop is R = 6.0 m, what is the minimum height h for which the roller coaster will not fall off the track at the top of the loop?...
