A 10 kg block press on a table the coefficient of static friction between the table and the block is 0.50 if someone pushes down on the block with a 48 N force what is the maximum horizontal force that will not move the block?

Respuesta :

Answer:

  73 N

Explanation:

You want the maximum horizontal force that will not move a 10 kg block being pressed to a table with a force of 48 N, given the coefficient of static friction is 0.50.

Friction force

The maximum static friction force is the product of the coefficient of friction and the normal force at the interface with the table. That normal force is the sum of the force due to gravity and the force being applied.

  F = µ(mg +f) = 0.50(10·9.8 +48) = 0.50(146) = 73 . . . . newtons

The maximum horizontal force is 73 N.
