Ball bearings can be 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 4.0 s to solidify enough for impact, how high must the tower be?
b. What is the bearing’s impact velocity?
Step 1 of 3:
The ball bearings fall inside a shot tower with zero initial speed. We are going to find the height of the shot tower required to land them in 4 s.
The initial speed vis = 0
The time taken by the ball Δt = 4 s
The acceleration due to gravity g = 9.8 m/s2
The final height at the ground y0 = 0
The initial height = y
