1. Two horses pull horizontally on ropes attached to astump. The two forces F1 and F2that they apply to the stump are bsuch that the net (resultant) force Rhas a magnitude equal to that F1 of and makes an angle of 90 degrees with F1.Let F1 = 1300 Nand R = 1300 Nalso. Find the magnitude of F2and its direction (relativeto F1)
2. A 4.80-kg bucket of water is accelerated upward by a cord of negligible mass whose breaking strength is 75.0 N. If thebucket starts from rest, (a) what is the maximum acceleration? (b) What is the minimum time required to raisethe bucket a vertical distance of 12.0 m without breaking the cord?
