Supposed Andra is pushing the same 50kg sled across the level terrain with a force of 50N. If she does 4 J of work on the sled whilst exerting the force horizontally, with what distance must she have pushed it? a. 8 meters b. 7 meters c. 6 meters d. 0 meters If Andra exerted the same force at angle 45 degrees with respect to the horizontal and moves the sled through the same distance, how much work does she do on the package? a. 283 J b. 256 J c. 271 J d. 291 J The coefficient of Kinetic Friction between the loaded 60kg sled and snow is 0.2. Andra pulls again the sled 9 meters, exerting a force of 1.3 N at angle of zero degree. Solve for the work done on the sled by the friction.
