a 33 kg lawnmower is pulled by a 100N force on flat ground. The handle makes a 10 degree angle with the ground. The coefficient of friction between grass and lawnmower wheels is 0.10.

Calculate normal force, force of friction and acceleration

notice there is a slight upward force on the lawnmower, this reduces weight and friction.
upwoard force= 100*sin10
friction= (33*g-100sin10)*mu
Net horizontal force=100cos10-frictonabove
acceleration=nethorizontalforce/mass
