1. The problem statement, all variables and given/known data A person pulls on a 20kg lawnmower with a force of 25.0N and moves the mower 4.50metes. The handle angle is 15* with the horizontal and μ=0.100. a) Work done by person √ = 109J B) Work done by friction √ = -85.3J C) Find the time ???? 2. Relevant equations P= W/T = W*(constant velocity) 3. The attempt at a solution I tried to use one of the power equations though I had 2 unknowns (P and T). I have no idea how to go about finding the time.
