A 42 kg slab rests on a frictionless floor. A 9.7 kg block rests on top of the slab. The coeff of static & kinectic friction is 0.53 and 0.43 resp. The 9.7 kg block is acted upon by a horizontal force of 110 N. Find acc. of block and slab. Explain with steps

Expert Answer
Applied force=110 N
limiting force, =mg
where m=mass of block=9.7kg
g=10m/
since F>,two bodies will move in the direction of applied force,but with different accelerations.
Force of dynamic friction,
where =coeff. of kinetic friction=0.43
This causes motion of slab,
for motion of block,
