What Is the Average Acceleration of a Baseball Hit by a Bat?

In summary, the problem involves determining the average acceleration of a baseball when hit by a bat at a specific speed and time. Using the given information and the equation a=v÷t, the average acceleration is calculated to be 2.0 x 10^5 mi/hr/s. This can also be expressed as -2.03×10^-3mi/hr/s.

Homework Statement

Need assistance with this problem.

Homer Agin leads the Varsity team in home runs. In a recent game, Homer hit a 96 mi/hr sinking curve ball head on, sending it off his bat in the exact opposite direction at 56 mi/hr. The actually contact between ball and bat lasted for 0.75 milliseconds. Determine the magnitude of the average acceleration of the ball during the contact with the bat. Express your answer in both mi/hr/s and in m/s/s. (Given: 1.00 m/s = 2.24 mi/hr)

Vf=-56mi/hr Vi=96mi/hr
t=7.5×10^4s

Homework Equations


a=v÷t

The Attempt at a Solution


(-56-96)÷7.5×10^4=-2.03×10^-3mi/hr/s

The answer to the problem on the link http://www.physicsclassroom.com/calcpad/1dkin/prob8.cfm says 2.0 x 10^5 mi/hr/s for one of the answers.

I think you simply plugged it in wrong, (-56-96)÷7.5×10^4 = 2.0 x 10^5
 

FAQ: What Is the Average Acceleration of a Baseball Hit by a Bat?

What is baseball acceleration?

Baseball acceleration refers to the rate at which a baseball player increases their speed while running or throwing the ball. It is an important aspect of the game as it allows players to reach their maximum potential and improve their performance on the field.

How is baseball acceleration measured?

Baseball acceleration can be measured using various methods such as radar guns, video analysis, and wearable technology. These tools can track the player's speed and acceleration in different situations, such as running to first base or throwing a pitch.

What factors influence baseball acceleration?

There are several factors that can influence baseball acceleration, including the player's physical fitness, technique, and reaction time. Other factors such as field conditions, equipment, and weather can also affect acceleration on the field.

How can baseball players improve their acceleration?

To improve baseball acceleration, players can focus on strength and conditioning exercises that target their legs, core, and arm muscles. They can also work on their technique and reaction time through drills and practice. Proper warm-up and stretching can also help prevent injuries and improve acceleration.

Is baseball acceleration important for all positions?

Yes, baseball acceleration is important for players in all positions. Infielders need to accelerate quickly to field ground balls and make throws to first base. Outfielders need to accelerate to catch fly balls and make throws to home plate. Even pitchers need acceleration to generate enough power for their pitches.
