1. The problem statement, all variables and given/known data A gardener pushes a 12 kg lawnmower whose handle is tilted up 37 deg above horizontal. The lawnmower's coefficient of rolling friction is 0.15 How much power does the gardener have to supply to push the lawnmower at a constant speed of 1.2 m/s Assume his push is parallel to the handle. 2. Relevant equations power = force x velocity 3. The attempt at a solution I know the answer is 24 joules but i cant get there the equation I used to find the force was F= [tex]\mu[/tex]kmg/ [tex]\mu[/tex]ksin[tex]\theta[/tex] + cos[tex]\theta[/tex] +sin[tex]\theta[/tex] i know its not right and i cant find the error thanks!!
