I have a flyweight that rotates about a pin in a cvt clutch.
the flyweight gets its motion from centrifugal force that acts on the center of gravity on the object. i am trying to develop the acceleration equation using kinamatics but am a little rusty. i have developed the force equations but would like help with the acceleration.

What work is done on a level track in bringing the velocity of a train weighing 200metric tons from zero to 45 kph, if the frictional resistance at any velocity is 45N/ton, and if the change in speed is accomplished in length of 1000m? (Ans. 26780.95 KN/m)

C. If the track were a 1% upgrade, what would be the additional work to be done?
