A1 200-kg car traveling initially at vci 5 25.0 m/s in an easterly direction crashes into the back of a 9 000-kg truck moving in the same direction at vti 5 20.0 m/s (fig. p9.22). the velocity of the car immediately after the collision is vcf 5 18.0 m/s to the east. (a) what is the velocity of the truck immediately after the colli

The velocity of the truck after the collision is 20.93 m/s

Explanation:

It is given that,

Mass of car, m₁ = 1200 kg

Initial velocity of the car,

Mass of truck, m₂ = 9000 kg

Initial velocity of the truck,

After the collision, velocity of the car,

Let is the velocity of the truck immediately after the collision. The momentum of the system remains conversed.

So, the velocity of the truck after the collision is 20.93 m/s. Hence, this is the required solution.

e) none of the above answers are correct

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
