Two identical 11.4-kg balls, each 27.6 cm in diameter, are suspended by two 35.0-cm wires as shown in the figure (Figure 1). The entire apparatus is supported by a single 18.0-cm wire, and the surfaces of the balls are perfectly smooth.
a) Find the tension in the top wire.
b) Find the tension in each of two bottom wires.
c) How hard does each ball push on the other one?

Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are v1i = +25.2 cm/s and v2i = ?20.1 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.) v1f = cm/s...
