A lawn mower weighs 1274 N. A person tries to push the mower up a hill that is inclined 15o
to the
horizontal. How much force does the person have to exert along the handle just to keep the mower from
rolling down the hill if the normal force exerted on the lawn mower by the ground is 1230.5 N, assuming
that the handle is parallel to the ground?

weight*cos15+forcepushing*sin15=1230.5
solve for force pushing
