Suppose we are moving a box from (0,0) to (6,0) using 3 lbs of force, but we are trying to decide at which angle to apply that force. (a) If we apply that force at an angle of 13 radians to the horizontal, what amount of (signed) work are we doing? (b) At what angle should we apply that force if we want to maximize the (signed) work done? How much work are we doing in that case? (c) At what angle should we apply that force if we want to minimize the (signed) work done? How much work are we doing in that case? (d) At what angle should we apply that force if we want to perform 0 units of work?
