You are pushing a 50 kg lawn mower with a force of 80 N at an angle of 45 degreesfrom the ground (the force points at 45 degreesinto the ground, like how you’d expect when you are pushing a lawn mower). What are the A) horizontal and B) vertical component of this force? The ground is pushing straight upwards at the lawn mower with some amount of normal force. The grassy lawn is also exerting a friction force against the...
