Physics

A car of mass M and a small truck of mass 3Mare travelling along two roads perpendicular to each other asshown.The car and the truck collide at the intersection atO.

The speed of the truck just before collision isVT =15.0m/s. Immediately after thecollision, the wreckage moves as a single mass withVf =12.0m/s as shown.

Using conservation of momentum:

[a] Find the value (indegrees) of θ?
