How Do You Calculate the Force of Friction on a Moving Cart?

[kurikat]

Homework Statement

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.

Homework Equations

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