What is the magnitude of x(t)

  1. Apr 9, 2009 #1
    1. The problem statement, all variables and given/known data
    A 18.0-kg block oscillates back and forth along a straight line on a frictionless horizontal surface. Its displacement from the origin is given by
    x(t) = (17.0 cm) cos[( 22.0 rad/s) t + π rad]

    What is the magnitude of x(t) when the block experiences its maximum acceleration?


    2. Relevant equations
    most are below


    3. The attempt at a solution
    i started to work backwords and solve for k but after that im lost since i thought k is what i should be solving for

    nm just realized it gave it to me in the problem you can delete this

    When the acceleration is maximum, x(t) is maximum i.e. a

    ya the original eq had it as the very first term it was 17cm
