A bowling ball weighing 71.2 N is attached to the ceiling by a 3.80 m rope. The ball is pulled to one side and released; it then swings back and forth like a pendulum. As the rope swings through its lowest point, the speed of the bowling ball is measured at 4.20 m/s. At that instant, find (a) the magnitude and direction of the acceleration of the bowling ball and (b) the tens on in the rope. Be sure to start with a free-body diagram.

6. 6. There are 1000 turns on the primary side of a transformer and 200 turns on thesecondary side. If 440 V are supplied to the primary winding, what is the voltageinduced in the secondary winding? Is this a step-up or step-down transformer?
7. 80 V are supplied to the primary winding of a transformer that has 50 turns. If thesecondary side has 50,000 turns, what is the voltage induced on the secondary side?Is this a step-up or step-down transformer?
8. There are 50 turns on the primary side of a transformer and 500 turns on thesecondary side. The current through the primary winding is 6 A. What is the turnsratio of this transformer? What is the current, in milliamps, through the secondarywinding?9. The current through the primary winding on a transformer is 5 A. There are 1000turns on the primary winding and 20 turns on the secondary winding. What is theturns ratio of this transformer? What is the current, in amps, through the secondarywinding?
