the impulse on the 2 kg car immediately after colliding with the other toy car, m , is 30 N west. what is the velocity of the car
To find the velocity of the car, we need to use the impulse-momentum theorem, which states that the impulse on an object is equal to the change in momentum of the object.
The impulse, given as 30 N west, can be written as:
Impulse = Force x time = change in momentum
Given that the mass of the car is 2 kg, we can find the change in momentum by rearranging the formula:
Change in momentum = impulse = Force x time
Change in momentum = 30 N x time
Since we do not have the time of the collision, we cannot calculate the exact velocity of the car. Time will be required to find the change in momentum and then compute the velocity using the formula:
Velocity = Change in momentum / mass
We can theoretically calculate the velocity once we know the time of the collision.
