The Kinematic Equations

Final Velocity equation Vx= Vx0+axt Displacement equation x=Vx0(t)+ ax(t)2 Timeless Equation Vx2=Vx02+2ax(x)

vx = final velocity (m/s) vx0 = initial velocity (m/s) ax= acceleration (m/s2) x = displacement (m) t=time (s)

Two objects, X and Y, accelerate from rest with the same constant acceleration. Object X accelerates for twice the time as object Y. Which of the following is true of these objects at the end of their respective periods of acceleration?

(A) Object X is moving at the same speed as object Y.

(B) Object X is moving four times faster than object Y.

(C) Object X has traveled the same distance as object Y.

(D) Object X has traveled twice as far as object Y.

(E) Object X has traveled four times as far as object Y.
