A car of mass 1800 kg is traveling east at 60 km/hr approaching an intersection. A large truck of mass 2400 kg is approaching the same intersection traveling north at 60 km/hr. After the collision, the car and the truck become tangled and move as a single object. Assume that it's a very slick road so that there is no friction between the vehicles and the ground. Use only MKS units.

Is the collision between the cars elastic or inelastic?

inelastic

Explanation:

given,

mass of car = 1800 Kg

speed of the car = 60 Km/h

mass of truck = 2400 Kg

speed of truck = 60 km/h

collides and tangled together to form as a single object.

This type of collision is called inelastic collision.

When an object is in inelastic collision there coefficient of restitution is 0.

coefficient of restitution is the ratio of the exit velocity to the approach velocity.

As both car and truck moves together so, the exit velocity is zero hence, coefficient of restitution is zero.

hence, the collision is inelastic.
