Question

Two cars are involved in a collision. Before the collision, Car A (mass = 650 kg) is travelling with a velocity of 20 m/s and Car B is stationary. After the collision, Car A moves with a velocity of 8 m/s and Car B with a velocity of 6 m/s. Use the principle of conservation of momentum to find the mass of Car B.

Answer 1

Answer:

let the mass of B is M ,

Then from the principal of conservation of momentum,

( 650× 20)= (8×650)+ (6×M)

or, M= 1300 kg (ans)
