Question

At what velocity will a 10,000 kg truck have the same momentum as a 4000kg car at 30 ms–1 ?​

Answer 1

Explanation:

The momentum of a 10,000 kg truck whose velocity is 20 m/s will be 11 500 kg mis.

Answer 2

● For the truck:

=>Let velocity be x.

=>Weight of the truck=10,000kg.

=> Momentum (M)=mass*velocity.

=>10,000*x.

=>10,000x.

● For the car:

=> Velocity=30ms-1.

=> Weight of the car=40,000kg.

=> Momentum (M)= mass*velocity.

=> 40,000*30.

=>12,00,000.

ATQ, Momentum of car= Momentum of truck.

=> 12,00,000=10,000x.

=> x= 12,00,000/10,000.

=> x= 120ms-1.
