You have a level track. You push a cart with mass = 1.12[kg].

You measure the initial velocity to be 0.57[m s-1].

2 seconds later, you measure the velocity to be 0.427[m s-1].

2. Relevant equations

What is the work (reported in mJ) that friction did on the cart?

3. The attempt at a solution

W(f)=F(f) x d
