(adsbygoogle = window.adsbygoogle || []).push({}); [SOLVED] Momentum - collision

1. The problem statement, all variables and given/known data

An object of mass 950kg travelling east collides with an object of mass 1900kg travelling north. The two objects then move off together at 16m/s in a direction of 24degrees east of north. Find their respective velocities prior to the collision.

2. Relevant equations

p = mv

3. The attempt at a solution

Momentum after collision = 2850 x 16 = 45600

As momentum is a vector, then breaking it into its components we get:

Object 1: 950 x v1 = (45600)cos24 ... v1=43.85m/s

Object 2: 1900 x v2 = (45600)sin 24... v2=9.76m/s

I thought this seemed simple enough, but apparently the answers are wrong... can anyone see where I might have made mistake, or am I just going about it the wrong way altogether?
