Your engineering department is asked to evaluate the performance of a new 370-hp sports car. You know that 27% of the engine's power can be converted to kinetic energy of the 1200 kg car, and that the power delivered is independent of the car's velocity. What do you report for the time it will take to accelerate from rest to 60 mph on a level road

The four giant gas points that are made primarily of lightweight elements are

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?
