If the engine applies a 424 N force, what is the minimum power (in watts) needed if friction is ignored?

Students may have also noticed a slight decrease in total energy, but this is incorrect data because CoE states that it should stay constant. e. From position 0cm through 44cm, the marble is gaining height and gaining velocity. (1. Position 130cm had the greatest velocity. c. From position 85cm through 130cm. the marble is gaining velocity. 2. Potential Energy and Kinetic Energy have a DIRECT relationship. 7:00 us 9 n \\ \\
