A baseball goes from zero to 40 m/s in 0.159 s.
What is its average acceleration?
Answer in units of m/s
2
a= changevelocity/time=40/.159 m/s^2
To find the average acceleration, we can use the formula:
Average acceleration = (Final velocity - Initial velocity) / Time
In this case, the initial velocity is zero, the final velocity is 40 m/s, and the time is 0.159 s.
Substituting the values into the formula, we get:
Average acceleration = (40 m/s - 0 m/s) / 0.159 s
Simplifying the equation gives us:
Average acceleration = 40 m/s / 0.159 s
Dividing 40 m/s by 0.159 s, we find:
Average acceleration = 251.572 m/s^2
Therefore, the average acceleration of the baseball is approximately 251.572 m/s^2.
