Sterling Archer, despite failing repeatedly at pole-vaulting, is determined to master theskill. He is holding a vaulting pole parallel to the ground. The pole is 5 m long. Archergrips the pole with his right hand 10 cm from the top end of the pole and with his lefthand 1 m from the top end of the pole. Although the pole is quite light (its mass is only2.5 kg), the forces that Archer must exert on the pole to maintain it in this position arequite large. How large are they? (Assume that Archer exerts only vertical—up ordown—forces on the horizontal pole and that the center of gravity of the pole is located atthe center of its length.)40.9 N downward65.4 N upward
