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

. Given- vf-112m/s, d-398m, Vi-0m/s (112 m/s)2 =

(0 m/s)2 + 2*(a)*(398 m)12544 m2/s2 = 0 m2/s2 + (796 m)*a12544 m2/s2 =

(796 m)*a(12544 m2/s2)/(796 m) = aa = 15.8 m/s26.

the bal will not change its velocity.
