Prof. K. took a Tesla Model S for a test drive. The car weighs 4,500 lb and can accelerate fra 0 to 60 mph in 2.27 seconds. The car has a 581 kW battery pack. Help Prof. K. determine th efficiency of the vehicle [Ans. to Check 55.5%]. Note: The equation we learned in class P = E ONLY APPLIES if velocity is constant. Use the steps below to guide your thought process. Develop a symbolic relationship for the force required to move the car forward. Compute the work done by the car (in Ib-ft). Calculate the power required to do this work (in kW).
