Ball bearing are made by letting spherical drops of molten metal fall inside a tall tower, and they solidify as they fall.

a) If a bearing needs 4.0s to solidify, how high must the tower be?

b) What is the bearing velocity when it reaches the bottom?

c) What mathematical relationship describes the ball's velocity vs time? Acceleration?

d) What mathematical relationship describes the ball's position vs. time?

I wasnt given any formulas and have never taken physics and have no idea where to start this. Any help to get started would be appreciated. Thanks
