Acceleration
Use the following equation to calculate acceleration and include a reference direction (direction
traveled).
Acceleration final velocity-starting velocity
time it takes to change velocity
Example:
A runner accelerates from a velocity of 5 miles/hour east until reaching a velocity of 10
miles/hour east in 20 seconds. What was the runner's acceleration?
8.
Equation:
Work:
Use above equation. a-10 mi/hr-5 mi/hr
20s
Answer:
25 mi/hr/s east
