Formula for velocity

Answer 1

V = d / t (or v = dd/dt & v = integral of acceleration with respect to time for physics involving calculus)

where V is velocity, d is displacement (distance traveled) and t is time.

vf = vi + a*t

(vf)^2 = (vi)^2 + 2*a*d

Where vf is final velocity, vi is initial velocity, and a is acceleration

v = p/m

Where p is object's momentum and m is object's mass
