Question

. A force of 50N applied to a crate to the horizontal surface is used to drag the crate through a distance 7m along the surface. If
the workdone in dragging the crate is 175J, the frictional force between the crate and the floor is?

Answer 1

Answer:

25N

Explanation:

w =F.S here iF represent net force which is F(applied)-Friction

so

175 = (50-f) ×7

50-f = 25

f = 25 N

so frictional force between crate and floor is 25 N
