Question

FIND THE COMPONENTS OF WEIGHT ALONG AND PERPENDICULAR TO A PLANE IF A MASS OF 4KG IS LYING ON THE PLANE MAKING AN ANGLE OF 60 DEGREE WITH THE HORIZONTAL

Answer 1

Answer:

W = mg = 4 * 10 = 40 N

Component along = mg sin @ = 40 * sin 60

                                = 20 √3 N

Component Perpendicular = mg cos @ = 40 * cos 60

                                              = 20 N

I hope it helps .
