Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.

displacement = find the distance between the initial starting point of an object and the final position of the object

velocity, well there is a lot of ways to calculate this...

if the acceleration isn't constant, use the conservation of energy

if it is constant

the average velocity is = Δx/Δt

calculate intial velocity: Δx= Vi (t) + 1/2 a t²

and Vf² = Vi² + 2ad

use these 3 equations to find acceleration too

you might also need to use F=ma to find acceleration
