A block of mass m slides down a frictionless ramp to a loop of radius R, also frictionless. It's initial height above the bottom of the loop is ?h = 3R and the block starts at rest. What is the magnitude of the normal force that the track of the loop exerts on the block at position 2? You can assume that the block is exactly at the horizontal height of the center of the loop when it reaches position...

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...
