A gardener pushes a lawn mower a distance of 1500 m mowing a yard. The handle of the mower makes an angle of 30° with the ground. The gardener exerts a force of 30.0 N along the handle of the mower (that is, at the 30° angle with respect to the ground). How much work does the gardener do mowing the lawn?

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 factory worker pushes a 29.3 kg crate a distance of 4.1 m along a level floor at constant velocity by pushing downward at an angle of 28 ∘ below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.25. 1) What magnitude of force must the worker apply to move the crate at constant velocity? 2) How much work is done on the crate by this force when the crate is pushed a distance of...

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...
