Question

IP A white-crowned sparrow flying horizontally with a speed of 1.70 m/s folds its wings and begins to drop in free fall
How far does the sparrow fall after traveling a horizontal distance of 0.400 m

Answer 1

well, it takes 0.4/1.7 = 0.235s to travel that distance.

now use your usual equation of motion to find the vertical distance fallen in that time.
