5. A uniform, 255-N rod that is 2.00m long carries a 225-N weight at its right end and an unknown weight W toward the left end. When W is placed 50.0cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 75.0cm from the right end. (a) Find W. (b) If W is now moved 25.0cm to the right, how far and in what direction must the fulcrum be moved to restore balance?
