The velocity of the rising ball as a function of time is V = -9.8 (m/s 2) t j and its position as aįunction of time is r = (4.9 m - ½ 9.8 (m/s 2) t 2) j. The velocity of the falling ball as a function of time is The speed of the falling ball as aįunction of time is v = 9.8 (m/s 2) t and the distance traveled is d = ½ 9.8 (m/s 2) t 2. The two balls thereforeĪssume the ball falls for 1 second. Window, it is already above the midway point. The speed of the ball thrown upwardsĭecreases linearly with time. Ground it covers less than half the distance and is still above the midpointīetween window and ground. Moves with the slowest speed near the window and with the fastest speed near The speed of the dropped ball increases linearly with time. Will reach the window at the same time the dropped ball reaches the ground. Location at the halfway point between the window and the ground, above thisīoth balls are accelerating. At some location the balls pass each other. Your friend throws the ball upward at the same time you drop yoursįrom the window. You now repeat the drop, but you have aįriend down on the street, who throws another ball upward with the same You drop a ball from a window on an upper floor of a building. Freely falling objects move with constant acceleration Its direction is downwards, towards the center of the earth. Near the surface of the earth all freely falling objectsĪccelerate at approximately the same rate. Systematic experiments on freely falling objects were carried out by
