A light spring with a force constant of 22 N/m is connected to a wall and to a 1.8-kg toy bulldozer. When the electric motor in the bulldozer is turned on, it stretches the spring for a distance of 35 cm before its tread begins to slip on the floor and it accelerates back towards the wall at a rate of 0.784 m/s2. What is the coefficient of dynamic friction between the treads and the floor?
