Ball bearings are made by letting spherical drops of molten metal fall inside a tall tower called a shot tower and solidify as they fall.(adsbygoogle = window.adsbygoogle || []).push({});

If a bearing needs 4.50 to solidify enough for impact, how high must the tower be?

What is the bearing's impact speed?

I got the answer for the first part correct it was 99.2

d=.5*9.8*4.5^2=99.2

but I am not sure how to approach the second part.....

What is the bearing's impact speed?

I search all over but couldn't find an equation could someone help me with that.

All I need is the equation.....thank you
