# A car accelerates uniformly from rest to a speed of 40.0 mi/h in 12.0 s. Find (a) the distance the car travels during this time and (b) the constant acceleration of the car.

(a)

To determine
The distance travelled by the car.

Explanation

Given Info: The initial velocity of the car is 0 , the final velocity of the car is 400â€‰mi/h , and the time taken by the car to accelerate is 12.0â€‰s .

Explanation:

The formula used to calculate the distance travelled by the car is,

Î”x=(v0+v2)t

Here,

t is the time

v is the final velocity of the car

v0 is the initial velocity of the car

Î”x is the distance travelled by the car

Substitute 0 for v0 , 400â€‰mi/h for v , and 12

(b)

To determine
The constant acceleration of the car.
