A 48.5-g toy car is released from rest on a frictionless track with a vertical loop of radius R. The initial height of the car is h = 4.45R.

(a) What is the speed of the car at the top of the vertical loop? (Use the following as necessary: R and g.)

(b) What is the magnitude of the normal force acting on the car at the top of the vertical loop?

  • Loop the loop

    A roller-coastercar may be represented by a block of mass 50.0 . The car is released from rest at a height h= 60.0 above the ground and slides along a frictionless track. The carencounters a loop of radius R= 20.0m at ground level, as shown. As you will learn in the course of this problem, the initial height 60.0m is great enough so thatthe car never loses contact with the track.Find an expression for the kinetic energy of the car...
