Consider a 100 kg box which is at the rest. Now,
two forces are applied to the box and it starts to
move. Consider F1 = 400 N and F2 = 500 N and 0
%3D
= 60. Here F2 is a horizontal force. Find (a) the
normal reaction force from ground (N), (b) the
velocity if it slides 5 m. Take coefficient of kinetic
friction to be 0.2. Assume g = 9.81 m/s2.
