Question

A child pulls on a rope attached to a sled with a force of 60 N. The

rope makes an angle of 40° to the ground. (a) Compute the

effective value of the pull tending to move the sled along the

ground. (b) Compute the force tending to lift the sled vertically.

Answer 1

a)

$F_x=F\cos40°=46~N,$

b)

$F_y=F\sin 40°=39~N.$
