If the block doesn't move up or down then the displacement in the direction of force due to gravity is zero.
So the work done by the gravity will be zero.

You apply a constant force ??? = (6??)???+ (?4??)???to a 5kg box that travels 2m in a direction 200° counterclockwise from the +x-axis. How much work does the force you apply do on the box?
John is pushing a 50 kg box with a force of 100 N. The maximum static frictional force is 125 N. a) Draw a free body diagram. b) What is the coefficient of friction between the box and ground? Suppose John then pushes the box with Sally on top of it, who is 80 kg. The box comes to a stop and Sally then holds a present of an unknown mass. The maximum static frictional force is found to be...
1a. A horizontally directed force of 100 N is used to pull a box a distance of 5 m. How much work is done by the force? What is the change of kinetic energy of the box? 1b. At the lowest point in its swing, a pendulum bob with a mass of 0.1 kg has a velocity of 2 m/s. Ignoring the resistance of the air, how high will the bob swing above the lowest point before reversing direction? g=10...
+x -Axi You pull a box 3 m along a frictionless horizontal surface with 5 N of force. You apply the force to a string attached to the top of the box at a angle of 30 degrees. How much work is done? Your Answer: Answer units
