Question

a 76.5N block is being held in place by static friction on a ramp that makes an angle of 35.7 degree with the horizontal. what is the magnitude of the normal force on the block ?

Answer 1

The magnitude of the normal force on the block:

$$N=W\cos{35.7 \degree}=76.5\cos{35.7 \degree}=62.1\ N$$
