How much work is done on the set? a. 2 J b. 10 J c. 20 J d. 40 J e. 80 J. Yahoo Answers is shutting down on May 4th, 2021 (Eastern Time) and beginning April 20th, 2021 (Eastern Time) the Yahoo Answers website will be in read-only mode.Work, force and distance are related to each other. When you apply a greater force, the work done and the distance travelled is high and vice versa. Work, force and acceleration are the basic concepts of travel and distance calculations in Physics. Enter the required values know the unknown value of work or force or distance.I'm going to show you some examples of how to solve problems involving work imagine a four kilogram trashcan the trashcan is disgusting so someone ties a string to it and pulls on the string with a force of 50 Newtons the force of kinetic friction on the trashcan while it slides is 30 Newtons the trashcan slides across the ground for a distance of 10 meters let's try to find the work done byThe work done in pushing a TV set a distance of 2 m with an average force of 20 N is A) 2 J. B) 10 J. C) 20 J. D) 40 J E) 800 J.Calculate the work done by a 2.0-N force (directed at a 30° angle to the vertical) to move a 500 gram box a horizontal distance of 400 cm across a rough floor at a constant speed of 0.5 m/s. (HINT: Be cautious with the units.)

The work done in pushing a tv set a distance of 2 m with an average force of 20 n is +1 Answers (1)work has been done by the centripetal force? A) 0 J B) 24 J C) 1000 J D) 6000 J E) 12000 J 13.A vertical force of 500 N acts on a 12 kg mass over a horizontal displacement of 2 m. The work done by the force is A) 25 J B) 50 J C) 86.67 J D) 14.4 J E) 35 J 14.A woman pushes a lawn mower with a force of F atby a pulley, where work done on M2 is used to lift M1 up the plane. For the object with a given mass m2 that moves downward, work is being done on the object by the force of gravity. The work done is simply the object's weight times the distance through which it moved: W2 = m2g S (eq. 6) Figure II. F = m2g M2 y2 y1 β S y2-y11. A TV set is pushed a distance of 2m with a force of 20 N that is in the same direction as the set moves. How Much work is done on the set? A. 10J B. 20J C. 40J D. 80J 2. A 1000kg car moving at 10m/s brakes to a stop in 5s. The average braking force is.....N? A. 1000 B. 2000 C. 4000 D. 5000 3. A 20kg mass is held 4m above the ground.

4 N b. 10 N c. 40 N d. 160 N e. none of these Answer: B This is a relatively simple plug-and-chug into the equation W=F*d*cos(Theta) with W=40 J and d=4 m and Theta = 0 degrees. 41. Using 1000 J of work, a toy elevator is raised from the ground floor to the second floor in 20 seconds.A tv set is pushed a distance of 2m with a force of 20N that is in the same direction as the set moves. how much work is - Answered by a verified Tutor We use cookies to give you the best possible experience on our website.The work done in pushing a TV set a distance of 2 m with an average force of 20 N is 40 J The work you do when pushing a shopping cart twice as far while applying the same force isthe work done in pushing a tv set a distance of 2 m with an average force of 20 n is a) 40j b) 10j c) 2400j d) 240j.
