Question

A11 Nhorizontal force F pushes a block kinetic friction is 0.40. Assume that the block is not weighing 36 N against a vertical wall (see the figure). The coefficient of statkc friction between the wall and the block is 0.60, and the coeffcient of moving initaly (al Will the block move?f'yes or no)0a) In unit vector notation F,i + Fj,what is the force onthe block from the wall? The coefficen ofsta b) Number Units

Answer 1

The block will move if the frictional force from the wall is lesser than its own weight

$F_f = \mu_sN = 0.60\times 11 = 6.6N$

The frictional force is greater than its own weight. Hence, the block will not move.

The force on the block by the wall will be

$F = -11\hat{i} + 6.6\hat{j}$
