Question

A baseball pitcher delivers a fast ball. During the throw, the speed of the ball increases from 0 to 30.0 m/s over a time of 0.100 seconds. The average acceleration of the baseball is ___m/s^2.

A) 3.00
B) 30.0
C) 300
D) 3000

Answer 1

The average acceleration of the baseball, which increases its speed from 0 to 30.0 m/s in 0.100 seconds, is calculated to be 300 m/s². The correct answer to the question is B) 300.

Step-by-step explanation:

The average acceleration of the baseball can be calculated using the formula:

a = Δv / Δt

where Δv is the change in velocity and Δt is the change in time.

In this case, the baseball's speed increases from 0 to 30.0 m/s over 0.100 seconds, so:

Δv = 30.0 m/s - 0 m/s = 30.0 m/s

Δt = 0.100 s

Plugging the values into the formula:

a = 30.0 m/s / 0.100 s = 300 m/s²

So the correct answer is B) 300.
