Please if you know how to solve it

Q.1 A man pulls box with a force of 60 N making an angle of 20o with the ground.

( a ) Determine the effective value of the pulling force to move the box along the ground.

( b ) Determine the effective value of the pulling force to lift the box vertically.

Question A: force=56.382N

Question B: force=20.52N

Explanation:

question A:

F=60N

Theta=20°

Force=F x cos(theta)

Force=60 x cos20 Cos20=0.9397

Force=60 x 0.9397

Force=56.382N

Question B:

F=60N

theta=20°

Force=F x sin(theta)

Force=60 x sin20 Sin20=0.3420

Force=60 x 0.3420

Force=20.52N

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
