Answer to Question #99396 in Physics for Nicky

Question

If a force of 50N moves a load of 20kg up an inclined plane . Determine the magnitude of the force if the plane is inclined at an angle of 30 degree.

Answer 1

The net force is

$$F_{net }=mg\sin{30}-F$$

$$F_{net }=(20)(9.8)\sin{30}-50=48\ N$$
