Newton’s second law

See on Scoop.itPHYSICAL SCIENCES BREAK 1.0

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 magnitude 150 N and a frictional force of magnitude 15 N is present, calculate the acceleration of the box.

 

Chipa Thomas Maimela‘s insight:

The motion is horizontal and therefore we will only consider the forces in a horizontal direction. Remember that vertical forces do not influence horizontal motion and vice versa.
