Answer:
fg = 352.8 N
fn = 352.8 N
Explanation:
Weight is also known as force of gravity
Because the object is at rest (no work) is done or in other words no frictional force.
Or Fnet= fn + fg = 0
so start with fg
fg= m x g
fg = 36 kg x 9.8m/s
fg = 352.8 N
Because the book is at rest, normal force will be the same
fn = 352.8 N
