Exercise 2.1

A man, of mass 75 kg, stands on a horizontal surface. Assume that the man has two points of contact with the ground.

a) Draw a diagram to show the forces acting on the man.

b) Calculate the magnitude of each of these forces.



Exercise 2.7

The mass of the moon is \displaystyle \text{7}.\text{38}\times \text{1}{{0}^{\text{22}}}\text{kg} and the radius of the moon is \displaystyle \text{1}.\text{73}\times \text{1}{{0}^{\text{6}}}\text{m} . Determine the acceleration due to gravity on the moon, by considering the force that the moon exerts on a particle of mass \displaystyle \text{1 kg} . on its surface.
