A square uniform raft, 20 m by 20 m , of mass 6400 kg , is used as a ferryboat. a)If three cars, each of mass 1150 kg , occupy the NE, SE, and SW corners, determine the coordinates of the CM of the loaded ferryboat relative to the center of the raft. Take the origin to be at the CM of the raft.
Three objects of mass m are lacated at threa corners of a square of edge length I, as shown in the diagram. The (xy) co-ordinates of the masses are (,0), (0,, and , al What is the direction of the gravitational acceleration at the origin? Express your answer in tearms of compass directions, taking the y-axis to be North. If the answer is "North", enter "N", if the answer is "Southwest enter "SW" Sit Arwer Tries 0/6 b) If m...
