A 1000 kg car moving a 10 m/s collides with a stationary 2000 kg truck. The two vehicles interlock as a result of the collision. What is the final velocity of the two combined vehicles?

3.33m/s

Explanation:

Given parameters:

M1  = 1000kg

V 1 = 10m/s

M2  = 2000kg

V2  = 0m/s

Unknown:

Final velocity of the two combined vehicles = ?

Solution:

This is a typical example of an inelastic collision.

 Here, it is pertinent that momentum must be conserved;

So;

       M1 V1 + M2 V2  = V (M1 + M2)

      1000 x 10  +  2000 x 0  = V (1000 + 2000)

                 10000 = 3000V

                     V  = 3.33m/s

3.2x10^7

im sorry i dont know
