Gravitational Potential Energy and Kinetic Energy
 

Gravitational Potential Energy and Kinetic Energy problem 28


An amusement park has a train that descends from a height of 30 m at the start of a ride. The mass of the train is 4.6 t. What is the velocity of the train after the first descent if it descends to a height of 5 m and the braking forces perform 0.23 MJ of work while running?
