Pete's mass is 64.7 kg. Construct a free-body diagram showing the forces acting upon Pete. Calculate the acceleration and net force acting upon Pete Zaria. Finally determine the coefficient of friction between Pete and the walls. This downward force must be balanced by the friction force since there is no vertical acceleration.
Acceleration is found from speed and radius.
Short Computations 21. From the equation, it can be deduced that a change in either one of the masses would produce a proportional change in the force of gravity. However, a change in the separation distance will produce the inverse square effect upon the force of gravity. So increasing separation distance by a factor of x, will decrease the force of gravity by a factor of x 2 . This reasoning leads to the following solutions.
