Use the back of each sheet if you run out of space. Cross over any parts that correspond to given up thoughts. For numerical answers give at least 2 significant digits and specify units. Assume g=10 m/s 2 throughout this exam. cos30 o =0.866, sin30 o =0.500 1. A crate of mass m=4 kg is being pulled on leveled floor with the force of 8 Newtons using a cord inclined by θ =30 o with respect to the floor (see picture below). Coefficient of kinetic friction between the crate and the floor is μ k =0.1. Assume g=10 m/s 2 throughout this problem. (a) Draw and label all forces on the block. (b) Find magnitude of the acceleration of the block. θ cord
