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
