The projectile will decelerate on its way to maximum height, come to a complete stop at maximum height, then starts its free fall descent towards the ground. Start practicing—and saving your progress—now: https://www. We can conclude that projectile motion is the superposition of two motions: the motion of a freely falling body in the vertical direction, and; uniform motion in the horizontal direction with constant velocity. In this motion, the object experiences two independent motions: horizontal motion (along the x-axis) and vertical motion (along the y-axis). 67 seconds. The average velocity is just equal to the average of these two numbers: so, minus 100 plus 0 over 2-- and I'm just averaging the numbers-- equals minus 50 meters per second.
