Extracted text: The 2.0-kg collar is at rest in position A when the constant force P is applied as shown. Determine the speed of the collar as it passes position B if P = 33 N. The curved rod lies in a vertical plane, and friction is negligible. K0.9 m- P 410 B 1.6 m 41° Part 1 How much work Up is done by the force P = 33 N on the collar? Answer: Up = i N•m
