    A box of mass 12 kg is placed in the back of a van. The coefficient of friction between the box and the floor is 0.6. What happens to the box if the lorry moves off with an acceleration of:

    (a) 4 ms^2
    (b) 6 ms^2
    (c) 8 ms^2

    (Take g = 10 ms^-2)

    Forces acting on the box are as follows:

    i) Weight mg downwards
    ii) Normal reaction N
    iii) Frictional force (forward dragging force) due to the floor of the van acting forward.
    iv) Inertial force (pseudo force) ma acting backwards (a = ...
