what is the acceleration of a car with velocity?
v = final velocity and u = starting velocity. Find the acceleration of a car, if it starts at 10 m/s and it reaches 30 m/s in 4 seconds. The change in velocity is v – u, which is 30 – 10 = 20 m/s. The acceleration is the change in velocity ÷ time, which is 20 m/s ÷ 4 s = 5 m/s 2.
