URGENT PLEASE... SAVE ME FROM THIS HW
An object at rest starts accelerating. If it travels 40 meters to end up going 20 m/s, what was its acceleration.
Answer: The car's acceleration is 5m/s^2 ^ 3.0 Explanation: The acceleration is the change in velocity per unit time. Here the initial velocity is O the final velocity is 20. So this formula is applicable. V^2= u^2 + 2as 20^2 = 0^2+ 2a (s)
