The force needed to accelerate a stationary 2000 racing car to a speed of 144 km/h in a distance of 80 meters

518400 Newton

Explanation:

Force F = mass m * Acceleration a

a = velocity v / time t

v = distance d / t

Therefore;

F = m * v² / d

with m = 2000 (unit not defined but say g)

v = 144 Km/h

d = 80 meters =0.08Km

F = 2Kg * 144Km/h * 144Km/h / 0.08Km

F = 518400 Newton
