1. ### 求高手 幫忙 摩擦力的問題?

Consider the 10 kg slab alone, use: net-force = mass x acceleration 100 - Ff = 10a ---------------- (1) where...10ug = 10a a = 10 - u.g ---------------- (2) If the block goes with the slab without any sliding, the block and slab have the same acceleration a. Hence...

2. ### mechanics [friction]

(i) I presume that the surfaces between the block and the slab are rough. Friction always opposes motion. When the...
