Question

A heavy box is pulled across a wooden floor with a rope. The rope forms an angle of

60 degrees with the floor. A tension of 80 N is maintained on the rope. What actually is
pulling the box across the floor?​

Answer 1

69.28N

Step-by-step explanation:

horizontal force

Cos 60°= F(horizontal)/80N

If we cross multiply, we have

F(horizontal)= 80 cos 60°

= 40N

vertical forces

Sin 60°= F(vertical)/80N

If we cross multiply we have

F( vertical) = 80 sin 60°

= 69.28N

Therefore, the vertical force is 69.28N
