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...

A boy pushes a lawn mower (m 17.9 kg) star ting from rest across a horiz ontallawn by applying a force of 32.9 N straight along the handle, which is inclinedat an angle of 35.1° above the horizontal
A boy pushes a lawn mower (m 17.9 kg) star ting from rest across a horiz ontallawn by applying a force of 32.9 N straight along the handle, which is inclinedat an angle of 35.1° above the horizontal. The magnitude of the mower’s accelerationis 1.37m/s 2, which lasts for 0.58 s, after which the mower moves at aconstant velocity. Determine the magnitude of(a) the normal force on the mower(b) the frictional force on the mower(c) the maximum velocity of...

2. A lawnmower of mass M = 6.5 kg moves across a lawn with a coefficient of friction Hk. The lawnmower is being pushed by a force, Fn = 36 N, along its handle which makes an angle 8 = 25° with the horizontal. If the lawnmower is moving at a constant velocity, what is the coefficient of friction, ik?
