impulse 2D question

Question

Kayden has a marble shooter and shoots a marble of mass 20.0 g at 350 m/s and the marble strikes a vertical steel plate at an angle of 30° with the plane of the plate, as shown in the figure. It bounces off the plate at the same angle but at a speed of 320 m/s. What is the magnitude of the impulse that the plate gives to the marble? report your units as kg*m/s
