After 3 seconds, the velocity of the object is 60 feet per second. What will be its velocity after 4- seconds? Assume that y varies directly as the square of x, and that when x=2, y=12. Determine y when x=8. The number of meters, d, that a skydiver falls before her parachute opens varies directly as the square of the time, t, that she is in the air. The skydiver falls 20 meters in 2 seconds. How far will she fall in 2.5 seconds?
