    A particle of mass 2 kg rests in limiting equilibrium on a plane inclined at 25 deg to the horizontal. Tha angle of inclination is decreased to 20 deg a force of 20N is applied up a line of greatest slope.

    Find the particles' acceleration. When the particle has been moving for 2 seconds the force is removed.

    Determine the further distance the particle will move up the plane.

    resolve perpendicular: R = 2g cos 25
    resolve parallel : Fr = 2g sin 25

    find fr/R=u
    -----------------------------------
    perpendicular : R = 2g cos 20, might have to include 20 N force here
    parallel: 20 - Fr = 2 a
    where Fr = UR
    -----------------------------------
    s=ut+(at^2 )/2
    u=0 a=... t=2 s=?
    -----------------------------------

    without drawing and assuming there is friction involved thats how i might do it
