Question

A 11 kg block is pulled at constant velocity by a rope.
The rope applies a force of F = 50 N at an angle of θ = 20 degrees above the horizontal as shown below.

(a) What is the horizontal (x) component of the pulling force F?
(b) What is the vertical (y) component of the pulling force F?
(c) What is the magnitude (strength) of the support force from the surface on the block?
(d) What is the magnitude (strength) of the frictional force retarding the motion of the block?

Answer 1

draw it please.

Answer 2

a) use cosine
b) use sine
c) weight of block minus answer at b
d) answer of question c divided by g*m
