(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

At time t = 0 a drag racer starts from rest at the origin and moves along a straight line with velocity given by v = 5t^2, where v is in m/s and t in s. The expression for the displacement of the car from t = 0 to time t is

(a) 5t^3

(b) 5t^3/3

(c) 10t

(d) 15t^2

(e) 5t/2

2. Relevant equations

(Vfinal-Vinitial/2)t=X

Vfinal=5t^2

3. The attempt at a solution

The manual says B

But I keep Getting 5t^3/2

Vfinal=5t^2

Vinitial=0

so

(5t^2/2)t=x

5t^3/2
