Question
A 9.00-kg particle moves from the origin to position ©,
having coordinates x = 4.50 m and y = 4.50 m as shown
in the figure. One force on the particle is the gravitational
force acting in the negative y direction. Using the
equation (W = FAr cos 0 = F · A:), calculate the work done
by the gravitational force in going from 0 to o along the
following paths.
