Calculating Car Acceleration
A car accelerates uniformly from rest to 25 m/s over a distance of 30 meters. What is the acceleration of the car?
Answer:
10.4 m/s²
Explanation:
Use the formula: V² = Vo² - 2aΔx
Plug in the known values then solve for a. Vo = 0 because the car starts from rest.
(25 m/s)² = 0 + 2a(30m)
a = (625 m²/s²)/(2)(30m) = 10.4 m/s²
a car accelerates uniformly from rest to 25 m/s over a distance of 30 meters. what is the acceleration of the car? 10.4 m/s²
