# Question #d0f95

##### 1 Answer

A truck and a car are going with the same velocity

Clearly momentum of the truck is greater than the momentum of the car

Because Momentum

Now brakes are applied at the same time.

Implies both the truck and the car are decelerated or retarded at the same time. The deceleration produced in each is given by Newton's second Law

We know from kinematics that final velocity

Inserting value of

Solving for distance we get

And as per initial conditions

From this relationship we can say that for the same retarding force

However, we need to specify specific values for the respective masses and braking powers to assess the situation.
