Conversions of a thrown basebal

In summary, the conversion rate of a thrown baseball is influenced by factors such as speed, angle, air resistance, gravity, and weight. On average, a baseball thrown at 90 mph will cover 132 feet in 1 second. Air resistance slows down a thrown baseball, and the optimal angle for maximum distance is around 45 degrees. Gravity causes the baseball to fall towards the ground, resulting in a curved trajectory. The weight of a baseball does not have a significant impact on its conversion, but a heavier or lighter ball may affect the pitcher's accuracy.

Homework Statement



a good baseball pitcher can throw a baseball toward home plate at 85 mi/h with a spin of 1800 rev/min. how many revolutions does the baseball make on its way to home plate? for simplicity, assume that the 60 ft path is a straight line.

Homework Equations





The Attempt at a Solution



First, we need to convert the unit from miles to feet. Since 1 mile = 5280 feet, 85 mi/h becomes 7480 ft/min.
And we need to do with 1800 rev/min. what should I do with it?

I got it.
1800 * 60 = 108000.
108000 / 7480 = 14.44
 

FAQ: Conversions of a thrown basebal

What is the conversion rate of a thrown baseball?

The conversion rate of a thrown baseball varies depending on the speed and angle at which it is thrown, as well as factors such as air resistance and gravity. However, on average, a baseball thrown at 90 mph will cover approximately 132 feet in 1 second.

How does air resistance affect the conversion of a thrown baseball?

Air resistance, also known as drag, slows down a thrown baseball and affects its trajectory. The higher the speed of the baseball, the greater the air resistance. This means that a baseball thrown at a higher speed will cover less distance than one thrown at a lower speed, all other factors being equal.

What is the optimal angle for throwing a baseball for maximum distance?

The optimal angle for throwing a baseball for maximum distance is around 45 degrees. This angle allows the baseball to achieve the greatest horizontal distance while also minimizing the effects of air resistance.

How does gravity affect the conversion of a thrown baseball?

Gravity constantly pulls on a thrown baseball, causing it to fall towards the ground. This means that the longer a baseball is in the air, the further it will drop. As a result, the trajectory of a thrown baseball is a curved path rather than a straight line.

How does the weight of a baseball affect its conversion when thrown?

The weight of a baseball does not have a significant effect on its conversion when thrown, as long as the weight falls within the standard range of 5 to 5.25 ounces. However, a heavier or lighter baseball may alter the pitcher's ability to control the ball and throw it accurately.
