Question

A person bends over to push a couch across the room. Their arms are

angled up at 18 degrees as they apply a 400N force. How hard are they
pushing the couch horizontally?

Answer 1

Step-by-step explanation:

The force along the horiozontal direction isexpressed as;

Fx = F cos theta

Given

F = 400N

theta = 18degrees

Substitute

Fx = 400 sin 18

Fx = 400(0.3090)

Fx = 123.61

Hence the force applied in the horizontal direction is 123.61N
