Impulse:

$\overline{){\mathbf{J}}{\mathbf{=}}{\mathbf{m}}{\mathbf{\u2206}}{\mathbf{v}}}$

**1. **

J = m(v_{f} - v_{0})

The initial velocity, v_{0} = v i

The final velocity, v_{f} = 2vj

1. Find the magnitude of the impulse J delivered to the particle. Express your answer in terms of m and v. Use three significant figures in the numerical coefficient.

2. Which of the vectors below best represents the direction of the impulse vector J?
