The power is the rate of work or rate of energy transfer. The Sl units for power are joule/second also known as a watt. The power provided by a force Facting on a object moving at velocity i is given by dW d P di -(F - AF) = F . = F.5 dt dt dt A force F = (31 – 2j)N acts on a particle traveling with velocity i = (4 î + 6j) m/s. a. What is the power generated by this force? b. Another way to calculate the scalar product is to use the angle between the vectors so P = ||F|| ||| cos o. Based on your result for part (a), what was the angle between F and D?
