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.

Young Hector launches a 200 gram block uphill on a frictionless ramp which is tilted at 30 degrees with the horizontal, as shown in the Figure. At the instant of its launch, the block is moving uphill at 4.00 m/s. Hector observes as the block travels a distance of 50.0 cm uphill on the ramp. In the following, consider the period of time during which the block moves uphill through the 50.0 cm distance shown in the Figure. For simplicity, assume that g = 9.80 m/2. d (50.0 cm) 4.00 m/s h 30°
