## Homework Statement

10. A red convertible of momentum mv travelling north on the Murdoch Drive collides, at the intersection of Murdoch Dr and South St, with a green sedan having the same magnitude of momentum, but travelling west on South St.

a. What is the magnitude and direction of the resulting momentum of the vehicles if it is an inelastic collision?

b. Calculate the resulting momentum if the mass of each vehicle is 2200kg and their initial speeds were both 14ms-1

## Homework Equations
