Acar accelerates from 5.0 m/s to to 11 m/s at a rate of 3.0 m/s^2. how far does it travel while accelerating? 20m 117m 43m 16m

As you know, there are some equation in physics to describe the motion of the bodies under a constant acceleration, they are called "The Equations of motion".

one of there equation has got a relation between the final velocity, initial velocity, acceleration and the distance.

in symbols:

where: is the final velocity, is the initial velocity, is the acceleration and is the distance
