Question

A heavy truck moving with 20 km/hr hits a car at rest. A physics student argued that

the maximum velocity the car suddenly gains is 40 km/hr. Do you agree with it?
Explain with necessary theory

Answer 1

Yes

Step-by-step explanation:

speed of truck = 20 km/h

Initially the car at rest.

maximum velocity of car = 40 km/h

When the truck and the car collide, the momentum of the truck transferred to car.

So, the car can attain the speed of 40 km/h.
