While sliding a couch across a floor, Andrea and Jennifer exert forces FA and FJ on the couch. Andrea’s force is due north with a magnitude of 130.0 N and Jennifer’s force is 32 east of north with a magnitude of 180.0 N. (a) Find the net force in component form. (b) Find the magnitude and direction of the net force. (c) If Andrea and Jennifer’s housemates, David and Stephanie, disagree with the move and want to prevent its relocation, with what combined forceFDS should they push so that the couch does not move?
The person in Figure P4.49 weighs 170. lb. Eachcrutch makes an angle of 22.0° with the vertical (as seen from thefront). Half of the person’s weight is supported by the crutches,the other half by the vertical forces exerted by the ground on his feet. Assuming he is atrest and the force exerted bythe ground on the crutchesacts along the crutches, determine(a) the smallest possiblecoefficient of friction betweencrutches and ground and(b) the magnitude of the compressionforce supported byeach crutch.
