73. At t = 0, the baseball player hits the ball with an initial velocity of 32 m/s and an angle of 55° with the horizontal range. A player 85 m from the hitter shoots at t = 0 and the line joining them makes a 22° angle with the ball's release line (see Figure 3-50) to catch the ball. What speed and direction must this player move to catch the ball at its same level of release?

A75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is to be replaced by a high-efficiency motor that has an efficiency of 95.4 percent. the motor operates 4368 hours a year at a load factor of 0.75. taking the cost of electricity to be $0.12/kwh, determine the amount of energy and money saved as a result of installing the high-efficiency motor instead of the standard motor. also, determine the simple payback period if the pu
