A1200 kg car traveling north at 10 m/s is rear-ended by a 2000 kg truck traveling at 30 m/s. what is the total momentum before and after the collision?

The total momentum before and after collision is 72000 kg-m/s.

Explanation:

Given that,

Mass of car = 1200 kg

Velocity of car = 10 m/s

Mass of truck = 2000 kg

Velocity of truck = 30 m/s

Using conservation of momentum

The total momentum before the collision is equal to the total momentum after collision.

Where, =mass of car

=velocity of car

=mass of truck

=velocity of truck

Put the value into the formula

Now, The total momentum before collision is

The total momentum after collision is

Hence, The total momentum before and after collision is 72000 kg-m/s.
