  • A1: Block has friction (static or kinetic)

    Question by Tom Stallard

    A block of given mass is sits on a flat plane with defined static and kinetic friction values. Randomly, it does one of two things, it is either:

    1) pushed with enough force to start it moving - calculate the force on the block or the static friction.

    2) moving over a distance - calculate the work done or the kinetic friction

    (are these uneven calculations)
