Calculate the work done by an 70.0-kg man who pushes a crate 4.50 m up along a ramp that makes an angle of 24.0° with the horizontal. (See figure below.) He exerts a force of 535 N on the crate parallel to the ramp and moves at a constant speed. Be certain to include the work he does on the crate and on his body to get up the ramp 1021.2J Enviar Respuesta Incorrecto. Tries 5/50 Intentos Anteriores

A worker pushes a 100 kg crate upward a distance 5.0 m along a frictionless conveyer that makes an angle of 30 degrees with the horizontal. The force she exerts is parallel to the conveyer. If the speed of the crate is constant, the work done by the worker is A 250 J B -2,500 J C 2,500 J D 500 J E -250 J F -500 J

A man pulls a 101.0 N crate up a frictionless ramp that is inclined at 0.9768 rad above the horizontal, starting at the bottom and going all the way to the top. The ramp is 5.143 m high, and the pulling force is parallel to the surface of the ramp. Assuming that the crate moves at a constant speed, calculate how much work did the man did on the crate. NOTE: Be sure to include units. W

A man pushing a crate of mass m = 92.0 kg at a speed of v = 0.845 m/s encounters a rough horizontal surface of length ℓ = 0.65 m as in the figure below. If the coefficient of kinetic friction between the crate and rough surface is 0.357 and he exerts a constant horizontal force of 292 N on the crate. A man pushes a crate labeled m, which moves with a velocity vector v to the right, on...

A crate of mass 40 kg is pushed up a ramp by a person as shown in the figure below. The person pushes the crate a distance of 30 m as measured along the ramp. Assume the crate moves at constant velocity. Assume the coefficient of kinetic friction between the crate and the ramp is μK = 0.30. Find the work done by gravity on the crate.
A factory worker pushes a 29.3 kg crate a distance of 4.1 m along a level...
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...
