Acar of mass 2kg is moving with 6m/s when collides with a second car of mass 3kg which is coming from opposite direction with 2m/s. the two cars lock together and move along the road. what is the speed of the cars immediately after collision?
3m/s
0m/s
1.2m/s
2.5m/s

Speed of the car after the collision is 1.2 m/s

Explanation:

It is given that,

Mass of first car, m₁ = 2 kg

Velocity of first car, v₁ = 6 m/s

Mass of second car, m₂ = 3 kg

Velocity of second car, v₂ = -2 m/s (it is travelling in opposite direction)

The two cars lock together and move along the road. This shows an inelastic collision. Let their common velocity is V. On applying the conservation of momentum as :

V = 1.2 m/s

So, after collision the speed of the cars is 1.2 m/s. Hence, this is the required solution.

answer; equivalent to a one(1) horsepower motor;

its a 5.5 n
