Q- A truck with mass 5000 kg is heading east at 20 m/s. Meanwhile a car with mass 2500 kg is heading north at 30 m/s. The two vehicles collide at an intersection, get stuck together and the wreckage keeps moving to some direction.
(a) Is the collision elastic or inelastic?
(b) Find the speed of the wreckage and the direction it moves to, just after the collision.
