Question

A horizontal force of 90 N is used to push a box across a horizontal floor. The frictional force on the box is 50 N. What is the resultant force the box experience due to those two forces?​

Answer 1

Answer:

40N

Explanation:

4 forces acting on a block

1 upward that is normal reaction

2 downward that is weight

3 that is applied force 90 N

4 that is frictional force 50N

:normal reaction is balanced by the weight of the block but the frictional. force is not equal to applied force

hence does not balace applied force

net force = applied force - frictional force

net force = 90N-50N

net force = 40N
