![]() ![]() He exerts a push of 200N on the handle at an angle of 60° to the horizontal and the lawnmower moves to the left. A man pushes a lawnmower of mass 50kg at a constant velocity over a horizontal lawn.The coefficient of friction between grass and lawnmower wheels is 0.10.Ĭalculate normal force, force of friction and acceleration The handle makes a 10 degree angle with the ground. a 33 kg lawnmower is pulled by a 100N force on flat ground.Your instructor may ask you to turn in this diagram. (a) Draw the free-body diagram showing all forces acting on the mower. How much power does the gardener have to supply to push the lawnmower at a constant speed of 1.5 m/s ? Assume his A person pushes a 15.0 kg lawn mower at constant speed with a force of 77.0 N directed along the handle, which is at an angle of 49.0 to the horizontal. The lawnmower's coefficient of rolling friction is 0.18. A gardener pushes a 17 kg lawnmower whose handle is tilted up 37∘Ībove horizontal.The left rope makes an angle of 150 degrees with the rod, and the right rope makes an angle theta I posted this before and didn't get an answer but I'm still stuck.Ī 3m long, 290N uniform rod is held in a horizontal position by two ropes at its ends.If the angle of incline is changed to 10º, how How large is the coefficient of kinetic friction if the plane makes an angle of 25 degrees with the horizontal? b. A wooden block slides directly down an inclined plane, at a constant velocity of 6 m/s.Ī. If the force used is 10N and the handle makes an angle of 25 degrees to the horizontal, what is the work done by the pulling force while the passenger walks 200m? a passenger at an airport pulls a rolling suitcase by its handle.Find the work done in pulling the toboggan 160 feet. A ski patroller pulls a rescue toboggan across a flat snow surface by exerting a force of 45 pounds on a handle that makes an angle of 22° with the horizontal.If the normal force exerted on the suitcase is 155 N, what is the force F applied to the handle? ![]() A 23 kg suitcase is being pulled with a constant speed by a handle that is at an angle of 25° above the horizontal.If the tension in the rope is 100 lb., what is the coefficient of friction? A 1200 lb sleigh is pulled along a horizontal surface at uniform speed by means of a rope that makes an angle of 30 degrees above the horizontal. ![]()
