Velocity = Distance (x) _______________ Time (t)1D A 1004Video Q 200Name one of the equation used to find displacement.

If you have the knowledge of time, initial velocity, and final velocityOR Initial velocity, time, and acceleration1D 300

2D 300Find the magnitude and direction of the displacement vector.Bx = -20 mBy = 10 mB1D A 300X = (vo + v)tX = vot + at^2ORWhat are the three equations that can be use for the X and Y direction to solve for distance and velocity?2D 100

vx = vox + axtvy = voy + ayt

vx^2 = vox^2 + 2ax xvy^2 = voy^2 + 2ay xX = voxt + axt^2Y = voyt + ayt^2
