Question:

A 5 kg lawn mower is being pushed with an applied force of F$$_a$$ = 20 N, at an angle of $$\theta$$ . There is a frictional force, F$$_f$$ opposing the movement of the lawn mower of 10 N. Given that the lawn mower is accelerating at 0.4 m/s$$^2$$:

• Find the angle $$\theta$$
• Find the magnitude of the normal force, F$$_N$$
