Question

An object at rest starts accelerating. If it travels 40 meters to end up going 20 m/s , what was its acceleration

Answer 1

5m/s^2

Step-by-step 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)
