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

An object starts from rest and has an acceleration given by

a = Bt^2 − 1/2Ct, where B = 4.5 m/s^4 and C = −2.2 m/s^3

(1) What is the object's velocity after 7.5 s? (Indicate the direction with the sign of your answer.)

(2) How far has the object moved after t = 7.5 s?

2. Relevant equations

v=at

3. The attempt at a solution

I integrated the equation its not coming out right

what am i doing wrong?

If someone can kindly explain.
