2 B 1 3. (20 pts.) A 45 kg steel block sits on a table. A load P is applied to the block at an angle 6 = 25 from the vertical. Determine: a. The magnitude of the force P required to start the block moving. (15) b. The magnitude of the force P required to keep the block moving at a constant velocity after the block begins to move. (5) C 0 P 0 = 25 s = 0.4 k = 0.34
