A person pushes a 22 kg lawn mower at a constant speed with a force of 91 N directed along the handle, which is 63° above the horizontal,
as shown.
a) Draw the force diagram of the lawn mower.
b) Determine the horizontal resistive force on the lawn mower.
c) Determine the normal force from the ground

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a. is a south pole because the field hnes spread out from this end b. a north pole because the field lines spread out from this end c. a nouth pole because the field lines enter the magnet at this end d. is a north pole because the field lines enter the magnet at this end
