A 7.00-9 part de moves from the origin to position having coordinates x 4.50 andy450 m as shown in the pure. One force on the particle is the gravitational force acting in the negative y direction. Using the equation W-Farcos F. ), calculate the work done by the gravitational force in going from o to along the following paths. of (m (a) the purple path (80 (b) the red path(DO the true path (0 (d) your should all be entic w
