1. The problem statement, all variables and given/known data

A 6.5 kg cart is pushed along a horizontal surface with a rightward force. After the cart is pushed a distance of 3.5 m starting from rest, its speed is 6.0 m/s. Find the force of friction acting on the cart.


2. Relevant equations
W=fd (?)
KE= 1/2(m)(v)^2 (?)
F_net=ma (?)


3. The attempt at a solution

Try to calculate the acceleration. You have an initial speed, a final speed and a distance.

Please show 3. The attempt at a solution. But first, the problem is missing information. You need to know the magnitude of the applied pushing force before the problem can be solved.
