An object at rest starts acceleraing . if it travels 40 meters to the end up going 20 m/s. what was its acceleration ?

The car's acceleration is 5m/s^2

Explanation: The acceleration is the change in velocity per unit time.

Here the initial velocity is 0 the final velocity is 20.

So this formula is applicable.

V^2= u^2 + 2as

20^2 = 0^2+ 2a (s)

answer; how far out of place which the object finished relative to the starting location;

answera compound;
