Acar with a mass of 1.2 × 103 kilograms is moving at a speed of 18 meters/second. it is hit by a truck from behind and its speed after the collision increases to 20 meters/second. what is the value of impulse?

Value of impulse is

Explanation: lmpulse is defined as the amount of force acting over a short time interval 't' which is equal to the change in momentum of the body having mass 'm'.

Mathematically,

And,

Given:

Putting values in above equation, we get:

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry
