A solid uniform 45.0-kg ball of diameter 32.0 cm is supported against a vertical, frictionless wall by a thin 30.0-cm wire of negligible mass (?Fig. P5.65?). (a) Draw a free-body diagram for the ball, and use the diagram to find the tension in the wire. (b) How hard does the ball push against the wall?

Solution 59P Step 1 : Let us draw a free body diagram Let us consider the data given Mass of the ball m = 45 kg Diameter of the ball d = 32cm This implies Radius of the ball is r = 16 cm Length of the wire = l = 30 cm
