A bat strikes a ball initially headed in the positive direction. The ball reverses direction after impact. The initial speed of the ball is 4 m/s, it’s mass is 0.5 kg, and it’s diameter is 0.1 m. What is the magnitude of the ball’s momentum before impact, in SI units?

A system hаs 10 servers S, S1, S2, …, S9. These servers cаn оnly serve up tо 9 clients simultаneоusly; otherwise, some have to wait for availability. All clients interact with server S, whose duty is to first check whether a server in need is idle. If yes, it forwards the data to the server for computation. The server S can also forward the computed result by the previous server to other servers for further computations. What design pattern is not very useful?
