## Homework Statement

An object is moving with a velocity by the equation

**v**(t) = [(3/2)(m/s

^{2})t] i

^{^}+ [(3/2)(m/s

^{3})t

^{2}] j

^{^}

What is the magnitude of displacement during 0 - 2s

## Homework Equations

**v**(t) = [(3/2)(m/s

^{2})t] i

^{^}+ [(3/2)(m/s

^{3})t

^{2}] j

^{^}

## The Attempt at a Solution

(3/2) ∫ from 0 to 2 [(t

^{2}/ 2) i

^{^}] + [t

^{3}/3]y^

plug and chug with t = 2

(3/2) √(squaring each of the i^ + j^)

I end up with some decimal answer which I know is wrong. Where am I screwing up?
