Chapter 6, Problem 90PP
The energy in a batted baseball comes from the power delivered while the bat is in contact with the ball. The most powerful hitters can supply some 10 horsepower during the brief contact time, propelling the ball to over 100 miles per hour. Figure 6.19 shows data taken from a particular hit, giving the power the bat delivers to the ball as a function of time.
FIGURE 6.19 Passage Problems 90-93
Which of the following is greatest at the peak of the curve?
- a. the ball's kinetic energy
- b. the ball's speed
- c. the rate at which the bat supplies energy to the ball
- d. the total work the bat has done on the ball
