## Homework Statement

A 15.0 g object initially moving to the right at 30.0 cm/s collides with a stationary 45.0 g object. After the collision the 45.0 g object is moving to the right at 15 cm/s.

what impulse does the 45.0 g object apply to the 15.0g object during collision?

## Homework Equations

F[tex]\Delta[/tex]t = m[tex]\Delta[/tex]v

## The Attempt at a Solution

I tried:

F[tex]\Delta[/tex]t = m[tex]\Delta[/tex]v

= (15.0g)(15.0cm/s)

= 225 N x s

but the answer is 6.75 x 10^-3 N x s

help ?
