Assume you push a 20kg child in a little red wagon with a force of 100N. However, the dirt and rocks below the wheels create a frictional force of 25 N. What is the acceleration on the wagon and child?

Abicycle slows down when the rider applies the brakes. what type of energy transformation is involved in this example? a. kinetic energy into heat energy b. heat energy into potential energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy
