Hello Everyone. I am almost through my on-line coarse on Introductory Physics. I am taking my last self-assessment before the on-line certification in two weeks. There is just one problem that has my confused. Please provide some guidance. Thanks. Accelerating Car - What is the average power required to accelerate a 1200 kg car from rest to a velocity of 20 m/s in 10 seconds? I am not even sure exactly where to start. I know that power can be measured in joules/sec a metric unit known as a watt. I do know some related formulas that might apply. They include: Power = Change in Energy/Change in time F = ma W = Fd I am still unclear how to proceed to determine that answer to this question in watts.
