Physics 125- Spring Semester ‘10 Kinematics Equations v = vo + at x = vot + 1/2at^2 x = ½(vo + v)t v^2 = vo^2 + 2ax 1. Free Fall…. A.)You drop a water balloon out your dorm window in efforts to hit your 1.8m tall roommate who is leaning against the wall directly below the window. You are on the fifth floor of West Quad, which sucks because there is no elevator, and it is 20m above the ground level. How long does your roommate have to move out of the way before they are hit with the balloon? If your roommate did not move, how fast would the balloon be moving when it reached your roommate’s head? B.) Your RA sees what is happening and is walking at a constant acceleration towards your roommate in order to push them out of the balloon’s path. If your RA starts walking at a distance of 3 meters away from your roommate, at what acceleration were they moving to just push your roommate out of the balloon’s path while sacrificing their own dryness?
