- 6. ** 23. Bob and his lazy brother, Will, are working together on a construction site, holding a triangular pane of glass as shown. The weight of the glass is 300 N. The center of gravity is indicated by a cross on the diagram. Both of the workers are pushing directly upward on the glass and the pane of glass is not moving. Find the upward force of each worker on the glass. - 200 N and I100 N 3 m 3 m 1 m 9 m- Bob WillPROBLEMI The 260kg crate shown in the figure rests on a horizontal surface for which the coefficient of kinetic friction is 025.
