Question

Jason is pulling a box across the room. He is pulling with a force of 15 newtons and his arm is making a 52 angle with the horizontal, what is the horizontal component of the force he is pulling with?

Answer 1

Draw a triangle with the 52^o angle from the ground. Total force 15N is the hypotenuse. COS ( 52^o) = adjacent/hypotenuse = horizontal force / 15N.

Horizontal Force = 15N * COS (52^o)

Make sure to draw the triangle. See how useful trig is!
