A hiker of weight 740N walks up a hill carrying a large bag of weight W. The hiker stops for a moment in the position shown. The normal force R of the ground on the hiker is the same at each foot. The frictional force between each foot and the ground is F. The hill is at an incline of 20° to the horizontal. The hiker repacks his bag, placing the heavier items at the bottom of the bag. Explain why this may cause R on the front foot to decrease

The normal force R of the ground on the hiker will decrease because of the inclination of the hill.

What is normal reaction?

The component of contact force normal to the surfaces in contact is called normal reaction.

Normal reaction depends on the weight of an object acting downwards and the normal reaction always act upward in the opposite direction of the weight of the object.

Normal reaction on the hiker

R = mg sinθ

R = 740 sin(20)

R = 675.6 N

Based on the inclination of the hill, the normal reaction on the hiker will reduce.

Thus, normal force R of the ground on the hiker will decrease because of the inclination of the hill.
