Consider pushing a lawn mower. Imagine that the lawn mower's handle was angled downward from the horizontal at 29.5 deg., and so when you push on the handle, you are actually pushing diagonally downward and forward at that angle. Assume that the push as 232.5 N. If the mass of the lawn mower is 23.4 kg and the effective coefficient of friction is 0.2, then calculate the magnitude of the lawn mower's acceleration
