A man is pulling a 20 kg box with a rope that makes an angle of 60 with the horizontal. If he applies a force of 150 N and a frictional force of 15 N is present, calculate the acceleration of the box.​

∑ F (horizontal) = (150 N) cos(60°) - 15 N = (20 kg) a

==>   a = ((150 N) cos(60°) - 15 N)/(20 kg) = 3 m/s²

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong
