Calculate how high must the tower be

Reference no: EM13525837

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.

(a) If a bearing needs 3.1 s to solidify enough for impact, how high must the tower be?

(b) What is the bearing's impact velocity? (Take up to be positive.)
