Agardener pushes a 20 kg lawnmower whose handle is tilted up 37∘ above horizontal. the lawnmower's coefficient of rolling friction is 0.18. how much power does the gardener have to supply to push the lawnmower at a constant speed of 1.5 m/s ? assume his push is parallel to the handle.

Ineed with these 2 questions. you.
