What was the speed of the van now before the collision

Reference no: EM13661021

A 1100 kg car which was moving at 12.0 m/s, was hit by a 1400kg van that was coming behind it. After collision both vehicles stick together and move forward. If their speed now after the collision was 16.5 m/s what was the speed of the van now before the collision (Suppose the road is frictionless).
