In baseball, a pitcher can accelerate a 0.17-kg ball from rest to 92 mi/h in a distance of a 1.7 m . What is the average force exerted on the ball during the pitch? If the mass of the ball is increased, is the force required of the pitcher increased, decreased, or unchanged? Explain.

A baseball catcher is catching a fastball that is thrown at 43 m/s (96 mi/h) by the pitcher. If the mass of the ball is 0.15 kg and if the catcher moves his mitt backward toward his body by 8.0 cm as the ball lands in the glove, what is the magnitude of the average force acting on the catcher's mitt? Estimate the time interval required for the catcher to move his hands.

8. One of the fastest recorded pitches in major league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h (Fig. P3.8). If a pitch were thrown horizontally with this veloc- ity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away? Figure P3.8 Tim Lincecum throws a baseball. 9·W The best leaper in the animal kingdom is the puma, which can jump to a height of 3.7 m when leaving...

1. In Major League Baseball, a typical fastball is pitched at a speed of about 90 mph, or 40 m/s. The batter can perform the remarkable task of completely reversing the direction of this ball and sending it back at about 105 mph, or 47 m/s. Doing this at just the right millisecond to get the ball to go where the batter wants it to go is such an amazing feat that a Yale physicist once jokingly declared that hitting...

1. A Vulcan spaceship has a mass of 6.50 × 104 kg and a Romulan spaceship is twice as massive. Both have engines that generate the same total force of 9.50 × 106 N. If each spaceship fires its engine for the same amount of time, starting from rest and ignoring any change in mass due to whatever is expelled by the engines, calculate the energy of the Vulcan spaceship if the engines are fired for 103 s. 2. A...
