A dragster accelerates to a speed of 112 m/s over a distance of 398 m. Determine the acceleration (assume uniform) of the dragster.

vi = 0 m/s

vf = 112 m/s

d = 398 m

Find:

(112 m/s)2 = (0 m/s)2 + 2*(a)*(398 m)

12544 m2/s2 = 0 m2/s2 + (796 m)*a

12544 m2/s2 = (796 m)*a

(12544 m2/s2)/(796 m) = a

a = 15.8 m/s2
