A trunk with a weight of 250N is at rest on a floor. The coefficients of friction between the trunk and floor are l-0.200 and Ps=0.350. a) What is the largest horizontal force that can be applied to the trunk for which the trunk wil not move? (Any force larger than this will start the trunk moving). b) Once the trunk is moving, what horizontal force is required to keep the trunk moving with a constant speed?
