A 1300 kg sports car accelerates from rest to 95 km/h in 7.4 s. What is the average power delivered by the engine?.

To calculate the power for this system, we use the formula given as:

Power = kinetic energy / time = 0.5mv^2 / t

where m is the mass, v is the velocity and t is the time. We calculate as follows:

Power = 0.5 (1300) ((95) (1000/3600)) ^2 / 7.4 = 61167.94 W = 61.17 kW
