## Homework Statement

Hey guys. I have a problem to solve but I am stacked and I don't now how,so any help will be hghly appreciated.The problem is the following: A truck of mass 9000kg is moving with speed 18m/s, when the driver decides to stop and applies the brakes. After 6s the truck stops. Assuming that the stopping is with constant deceleration calculate the followin:

a)The distance traveled by the car during stopping

b)The acceleration of the truck

c)The loss of energy due to friction

I would be grateful if you can give me some ideas using energy mostly but I wouldn't mind if you tell me another way through Newton Laws e.t.c!

## Homework Equations

## The Attempt at a Solution

So I personally started (a) by finding the acceleration through Newton's Second law a=F/m...Then I used v^2/2a to define the distance traveled (S)...So i found the acceleration in question (a) so (b) is ready as well i think..I don't know what to do in (c) though
