What do you think it should be?
HallsofIvy said:Your "kinematic equations" refer to the vertical motion only. You say the ball is thrown horizontally so the initial vertical component is 0. The height of the ball, at time t, is [itex]y= (1/2)(9.81)t^2+ 4[/itex]. Set that equal to 0 (the ball hits the ground) and solve for t to find when the ball hits the ground.
Taking "v" as the horizontal component of velocity, the distance the ball traveled, in time t, is given by x= vt. Put x= 25, t equal to the time you solved for above, and solve for v.
That, of course, is ignoring air resistance- which is fairly large for a baseball.
The speed of the pitch refers to the velocity at which a thrown ball travels towards the batter in a game of baseball. It is typically measured in miles per hour (mph).
The speed of the pitch is measured using a radar gun, which emits microwaves to calculate the speed of the ball as it passes by. This technology is also used in other sports such as tennis and cricket.
The average speed of a pitch in professional baseball is around 90-95 mph, but it can vary depending on the pitcher's strength and technique.
Yes, the speed of the pitch can be controlled by the pitcher through their arm strength, release point, and grip on the ball. They can also vary the speed of their pitches to throw off the batter's timing.
The speed of the pitch can greatly affect the outcome of a game as it can make it more difficult for the batter to hit the ball. A faster pitch is also more challenging for the catcher to catch, potentially resulting in errors or stolen bases by the opposing team.
