Problem 1 You are designing a roller coaster, shown in the figure below. An empty car has a mass of 120 kg. The radius of the vertical loop in the track is 12.0 m and the bottom of the loop is 5.0 m above the ground. Assuming the roller coaster is frictionless, how high must the car initially climb above the ground (point A) such that the speed of the car is 25.0 m/s at 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 box slides from rest down a frictionless ramp inclined at 38.0° with respect to the horizontal and is stopped at the bottom of the ramp by a spring with a spring constant of k = 2.00 x 104 N/m. If the box has a mass of 12.0 kg and slides 3.00 m from the point of release to the point where it comes to rest against the spring, determine the compression of the spring when the box comes to...

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...
