Question

A race car accelerates from 0 m/s to 30.0 m/s with a displacement of .25 km. what is the vehicle's acceleration?

Answer 1

Answer:

The acceleration of the car, a = 60 m/s²

Explanation:

Given data,

The initial velocity of the car, u = 0 m/s

The final velocity of the car, v = 30 m/s

The displacement of the car, s = 0.25 km

Using the III equations of motion

                    v² = u² + 2as

                     a = (v² - u²) / 2s

                        = 30 / 2 x 0.25

                        = 60 m/s²

Hence, the acceleration of the car, a = 60 m/s²
