Question

a car accelerates uniformly from rest to 25 m/s over a distance of 30 meters. what is the acceleration of the car?

Answer 1

10.4 m/s²

Step-by-step 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
