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)© BrainMass Inc. brainmass.com March 4, 2021, 11:01 pm ad1c9bdddf
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 = ...
