Displacement Formulas - How to Calculate Displacement

Displacement is defined as the shortest distance between two points. In a two dimensional system, distance formula can be used to find the shortest distance between two points. I.e.
If an object is moving with constant velocity, then Displacement = velocity x time
If an object is moving with constant acceleration then the equations of motion used to find displacement is:
S = ut + ½ at^{2}
If v = instantaneous velocity, Then Displacement (S) = ∫v(t)dt
Example: Find the displacement covered by an object which accelerates from rest to 60 m/s in 3s.
Ans: Initial velocity = 0 and final velocity = 60m/s Time taken = 3s. Therefore, acceleration = 60/3 = 20m/s^{2} Displacement (S) = ut + ½ at^{2} = 90m
Question: Find the displacement of an object if it moves with an acceleration of 4 m/s^{2} for 5s, where the initial velocity was 2 m/s.
