Question

how do you find velocity and acceleration ?

Answer 1

u can find velocity and acceleration by derived speed formula. see at the physics terms.

Answer 2

You need suvat, ie :
v^2=u^2+2as
v=u+at
s=0.5(u+v)t
s=ut+0.5at^2

s = displacement
u = initial veloicty (@ t=0)
v = final velocity
a = acceleration
t = time
