Nikola Tesla used rotating magnetic fields to generate, transmit, and use AC (alternating current). Today alternating current has replaced direct current in most situations.

an airplane drops a 100 kg package of supplies for a town in need. the airplane is flying 600 m above the ground. What is the acceleration of this supply package as it is released?

An engine absorbs 2150 J as heat from a hot reservoir and gives off 750 J as heat to a cold reservoir during each cycle. What is the efficiency of the engine?

A small 25 kilogram canoe is floating downriver at a speed of 4 m/s. What is the canoe's kinetic energy?

A car traveling on a flat (unbanked), circular track accelerates uniformly from rest with a tangential acceleration of 1.85 m/s2. The car makes it one quarter of the way around the circle before it skids off the track.
