A scientist flying above the ocean drops buoys into the water to track ocean currents. The plane is flying at a height of 500 meters horizontally at a constant velocity while the scientist drops the buoys straight down. After the buoy is dropped the plane travels a horizontal distance of 400 meters. How far vertically does the buoy fall?

How far horizontally does the buoy move before hitting the water?

How long does it take the buoy to hit the water?

How fast is the buoy moving horizontally?

THANK YOU !
