Assuming a baseball player’s home run leaves his bat at an angle of 54 degrees to the horizontal and a speed of 93 miles per hour, would it travel far enough to splash down in
McCovey Cove outside AT&T Park？
Assume McCovey Cove is 420 feet away. Also ignore any aerodynamic effects from the spin of the ball or air resistance (so the ball’s flight will be symmetrical), and assume that the water is at the same elevation as the batter's box. Use g = 32.2 feet per second squared for the acceleration due to gravity.
calculate the number of feet traveled to one decimal place？
Also calculate the maximum height (in feet) that the ball reaches and how long (in seconds) it's in the air？
Finally, assuming that this is an average home run swing for
the player, and that his average home run ball in reality usually travels 400 feet, calculate how much percentage effect air resistance has on a home run？
That is, the home run described above would normally travel 400 feet, but you came up with a different distance because you ignored air resistance. So by what percentage does air resistance decrease the length of the home run？ (This is a percentage error calculation, where the true value is 400 feet, and the calculated value is whatever number you calculated for the distance？
问题不太明白，不太了解base ball 的说－－
首先那个home run, 然后McCovey Cove 是个目标，或者地方之类吧？
还有个为什么那里有个WATER－－
问题也有N个－－了解base ball和Physics 指教一下吧！
