Question

A string exerts a force of 20 N on a box at an angle of 38° from the horizontal. What is the horizontal

Answer 1

Answer:

15.76N

Explanation:

horizontal component =Fcos¢ = 20cos38 = 15.76N

Answer 2

horizontal component = Fx = F cos α

vertical component = Fy = F sin α

the horizontal component of the force on the box:

$\tt =20\times cos~38^o\\\\=\boxed{\bold{15.76~N}}$
