A 2.5-kg block slides down a 25° inclined plane with constant acceleration. The block starts from rest at the top. At the bottom, its velocity is 0.65 m/s. The incline is 1.6 m long.
1. What is the acceleration of the block?
2. What is the coefficient of friction?
3. Does the result of either a or b depend on the mass of the block?
When Capacitor C1 having voltage V is connected with another capacitor C2 having zero charge in parallel with C1 what would be the dissipated energy.

An inquisitive physics student and mountain climber climbs a 55 m cliff that overhangs a calm pool of water. She throws two stones vertically downward 0.8 s apart and observes that they cause a single splash.
Upon and following the introduction of Coulomb's law, my book keeps referencing to the electric force experienced between two point particles as just that--between two point particles. Does mass affect Coulombs law in any way?
A uniform plank of length 4.50 m and weight 275 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support. To what distance x can a person who weighs 456 N walk on the overhanging part of the plank before it just be..
