Abullet is fired through a 14.0 cm thick board, with its line of motion perpendicular to the face of the board. if it enters with a speed of 450 m/s and emerges 220m/s, what is the bullet’s acceleration as it passes through the board?

The two required components for a generator

How is zig zagging a form of acceleration?

Consider a production line with five stations. station 1 can produce a unit in 9 minutes. station 2 can produce a unit in 10 minutes. station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. station 4 can produce a unit in 5 minutes. station 5 can produce a unit in 8 minutes. which station is the bottleneck station?
