A. The minute hand on a watch is 2.0 cm long.

1. What is the y-component of the displacement vector of the tip of the minute hand from 8:00 to 8:20 A.M.?

2. What is the displacement vector of the tip of the minute hand from 8:00 to 9:00 a.m.?

B. When striking, the pike, a predatory fish, can accelerate from rest to a speed of 3.7 m/s in 0.11 s.

1. How far does the pike move during this strike?

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

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

What is the bearing’s impact velocity?
