Concept explainers

Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.

4. This Olympic skeleton athlete slides down an icy track head first. The track has many twists and turns with a total height of 102.75 m. If the 99.375 kg man has a speed of 27 m/s at the bottom, what was the total work done on him by friction and air resistance slowing him down? (In other words, what was the energy lost to friction and air resistance?) He starts from rest at the top. Previous submissions:
Assume that before the accident happened, the car was going at a constant velocity of 60Km/h on a level highway for a distance of 10.0km. The car accelerated briefly to 70.0Km/h to pass another car and then returns to 60.0Km/h as it descends the other side of the hill, even though the driver has taken her foot off the accelerator.
