A 145 Kg Baseball Pitched At?
Contents
A 145 kg baseball pitched at 100 mph has the same kinetic energy as a 5 kg automobile moving at 500 km/h.
Introduction
A 145 kg baseball pitched at 90 km/hr hits a wall 45 m away. If the ball was in contact with the bat for 0.020 s, find the average force exerted by the bat on the ball.
What is the record for the fastest baseball pitch?
The record for the fastest baseball pitch is 164.7 km/h (102.5 mph), set by Aroldis Chapman in 2010.
How does the weight of the baseball affect the pitch?
There is no definitive answer to this question as the weight of the baseball can affect the pitch in a number of ways. A heavier baseball may require more effort to throw, resulting in a slower pitch, while a lighter baseball may be easier to throw and result in a faster pitch. In addition, the weight of the baseball can affect the spin rate, which in turn can affect the movement of the pitch. Ultimately, it is up to the pitcher to experiment with different weights and find what works best for them.
How does the size of the baseball affect the pitch?
The size of the baseball will affect the pitch in a number of ways. First, the larger the baseball, the greater the mass. This means that the ball will have more momentum and will be more difficult to stop. Second, the larger the baseball, the greater the surface area. This means that there will be more friction between the ball and the air, which will resist the motion of the ball and slow it down. Finally, the larger the baseball, the greater its moment of inertia. This means that it will take longer for the ball to rotate around its axis of rotation, and this will also resist its motion and slow it down.
How does the type of baseball affect the pitch?
The weight and size of a baseball can affect the pitch. A 145 kg baseball will have a different effect on the pitch than a smaller baseball.
Conclusion
In order to determine how fast a 145 kg baseball pitch, we need to know two things: the mass of the baseball and the speed at which it is pitched. With that information, we can use the following equation to calculate the speed of the ball:
v = sqrt(2*m*g/r)
where v is the speed of the ball, m is the mass of the ball, g is the acceleration due to gravity, and r is the radius of the ball. Plugging in our values, we get:
v = sqrt(2*145 kg*9.8 m/s^2/0.15 m)
= sqrt(4190 kg*m/s^2/0.15 m)
= sqrt(279333.33 kg*m/s^2)
= 522.6 m/s
This means that a 145 kg baseball pitched at a speed of 522.6 m/s would have an impact force of 145 kg * 9.8 m/s^2 = 1423 Newtons.
