Assignment Help Physics
Reference no: EM13657020

Ball bearings can be made by letting spherical drops of molten metal fall in a tall tower - called a shot tower - and solidify as they fall.

1. If a bearing needs 4.0s to solidify enough for impact, how high should the tower be?

2. What is the bearing's impact velocity?
