Asked by Alejandra

A 3.0 kg block is pushed along a horizontal floor by a force F of magnitude 19 N at an angle θ = 30° with the horizontal. The coefficient of kinetic friction between the block and floor is 0.25.(a) Calculate the magnitude of the frictional force on the block from the floor.(b) Calculate the magnitude of the acceleration of the block.

Fnormal= 19sin30+mg=38.9 N
a)friction = u Fnormal = 0.25x38.9 = 9.73 N

b) a =( 19cos30 -Friction)/m
=2.24m/s/s
