A baseball player tosses the ball to his teammate. When the ball first makes contact with the teammate's glove, the ball is traveling at 10 mph. The teammate stops the motion of both his glove and the ball 1 second later. What is the magnitude of acceleration on the ball in mph/minute?

Question

Quizplus · Accepted Answer

Step 1: Find the acceleration
Acceleration (a) = Change in Velocity (dV) / Change in Time (dt)
a = dV / dt
To solve for dV, subtract v1 (the original velocity) and v0 (the ending velocity)
dV = 0 mph - 10 mph = -10 mph
Next, solve for a:
a = -10 mph / 1 seconds = 10 mph / second
Step 2: Convert units:
-10 mph/s × 60 seconds = -600 mph/minute
Note: 
The question asks for the magnitude of acceleration. So, the answer is the absolute value of the acceleration:
|-600 mph minute| = 600 mph/minute
