Question

How to find average acceleration only using displacement and time?

Answer 1

Answer:

Average acceleration = Displacement / (time)^2

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.

Answer 2

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
