Question

a 50 kg slab rates on a frictionless floor of 10 kg block list of top of slab at the coefficient of static between the block and the slab is 0.7 the coefficient of kinetic between the block and slab is 0.5. the 10 kg is acted upon by a horizontal force of 100 Newton the resulting acceleration of the slab will be

Answer 1

hi mark it as brainliesthi bro it is simple just need a calculator answer is this The force F acting on the block has a magnitude of 110 N, and is greater than the static force of friction. Therefore the block slides on one another.
(a)
Apply Newton’s second law of motion to block,


= 7.61 m/s2
Round off to two significant figures so 7.6 acceleration of a block
Therefore, the acceleration of the slab is 0.86 m/s2
