Juan, Jose, and Jokoy are pushing a table with a constant 579 N force. Juan is pushing the table eastward while Jose is pushing northward. Jokoy is pushing in the 79° north of east direction. If the table moves 7 meters along east, how many joules of total work are exerted by the three men?

A child pulls a toy 2.8 m across the floor by a string, applying a force of constant magnitude 0.950 N. During the first 1.4 m the string is parallel to the floor. During the second 1.4 meter the string makes an angle 42.0 degrees with the horizontal. What is the total work done by the child on the toy in joules?

A person pulls a crate 46.1 meters along a horizontal floor by a constant force 102 N, which acts at 37.2 degrees. The floor is rough and exerts a friction force 50.8 N. What is the total net work done on the crate?

To push a 26.0 kg crate up a frictionless incline, angled at 25.0° to the horizontal, a worker exerts a force of 209 N parallel to the incline. As the crate slides 1.6 m, how much work is done on the crate by (a) the worker's applied force, (b) the gravitational force on the crate, and (c) the normal force exerted by the incline on the crate? (d) What is the total work done on the crate? (a) Number i Units (b) Number i Units (c) Number i Units (d) Number i Units > > >

Three men are pushing a table with a constant 421 N force. The first man is pushing the table eastward while the second is pushing northward. The third is pushing in the 74° north of east direction. If the table moves 7 meters along east, how many joules of total work are exerted by the three men.

An airplane flies 200 m at a constant altitude in a direction 30.0° south of east. A wind is blowing that results in a net horizontal force on the plane due to the air of 3.0 N in a direction 30.0° north of west. How much work is done on the plane by the air?

A person pushes a 19.6-kg shopping cart at a constant velocity for a distance of 15.1 m on a flat horizontal surface. She pushes in a direction 27.0° below the horizontal. A 52.0-N frictional force opposes the motion of the cart. (a) What is the magnitude of the force that the shopper exerts? Determine the work done by (b) the pushing force, (c) the frictional force, and (d) the gravitational force. (a) Number i Units (b) Number Units (c) Number i Units (d) Number Units

Juan, Jose, and Jokoy are pushing a table with a constant 452 N force. Juan is pushing the table eastward while Jose is pushing northward. Jokoy is pushing in the 77° north of east direction. If the table moves 9 meters along east, how many joules of total work are exerted by the three men. Input the value only; do not include the units.

An object moves in the x-y plane while acted on by the force F(x,y) = k1yi + k2xj, where k1 and k2 are constants with units of N/m. The object moves along a straight line path from Cartesian coordinate (x1, y1) to (x2, y2). Write an expression for the work done on the object by this force.

Jim rides his skateboard down a ramp that is in the shape of a quarter circle with a radius of 5.00 m. At the bottom of the ramp, Jim is moving at 9.00 m/s. Jim and his skateboard have a mass of 73.8 kg. How much work is done by friction as the skateboard goes down the ramp?
