1. The problem statement, all variables and given/known data A 2 kg box is given a brief push so that it slides across the floor, but the applied force is only applied for an instant. The coefficient of friction is 0.20 and the initial speed of the box is 4 m/s. Find acceleration of the box after the push Find how far the box goes before coming to rest. 2. Relevant equations Net force= mass*accel Friction=u*normal 3. The attempt at a solution I created an FBD, found the weight is 19.6N(9.8*2), and because it is being pushed horizontally, the Normal force is also 19.6 N. With the normal force I can find the force of friction. F=un, which means F=.2(19.6), and F=3.92 N. This leaves me missing the force I would need to calculate the Net f and find the accleration. I could only get this far, as I do not know how to find a force with only the velocity, mass, and friction.
