Michael pushes on the handle of a 12-kg lawn mower. The force of friction between the mower and the grass is 9 N. The handle makes a 35° angle with the horizontal. Michael wants to accelerate the mower at a rate of 0.8m/s2. What force must he apply along the handle?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
