You can't. You can only find average velocity.

But if you also know that initial velocity is zero ... the object started from rest ... then

Avg acceleration =

2 x displacement / time-squared

Answer:

Average acceleration = Displacement / (time)^2

Step-by-step explanation:

The unit for acceleration is

$m {s}^( - 2)$

Displacement = m

Time = s

Hence the units of displacement and time should be manipulated to get the unit of acceleration.
