Problem 1 A force of 200 N is exerted at an angle of 30° on the box kept on the floor with the coefficient of static friction of 0.2. Find the force of static friction on the box, when the force F is applied. F=100N Block Problem 2 A machine at a post office sends packages out a chute and down a ramp to be loaded into delivery vehicles. (a) Calculate the acceleration of a box heading down a 10.0°10.0° slope, assuming the coefficient of friction for a parcel on waxed wood is 0.100. (b) Find the angle of the slope down which this box could move at a constant velocity. You can neglect air resistance in both parts.
