A 1400 Kg Sports Car Accelerates From Rest To 95

A 1400 kg sports car accelerates from rest to 95 km/h in 5.0 seconds. The average acceleration during this time interval is

a = (95 km/h – 0 km/h)/(5.0 s – 0 s)

a = 95 km/h/5.0 s

a = 19 m/s2

The average force exerted on the car during this time interval is

F = ma

F = 1400 kg * 19 m/s2

F = 26600 N
