Calculate the work done by a 47 n force pushing a pencil 0. 26 m. 12. 22j: calculate the work done by a 47 n force pushing a 0. 025 kg pencil 0. 25 m against a force of 23 n. 12. 22j by 47n force, 6j by 23n force, 6. 22j net: calculate the work done by a 2. 4 n force pushing a 400 g sandwich across a table 0. 75 m wide. 2n: a girl pushes her little brother on his sled with a force of 300 n for 750 m. How much work is this if the force of friction acting on the sled is (a) 200 n, 225000j in both cases: a 75. 0 kg man pushes on a 500,000 t wall for 250 s but it does not move. 0, 5997. 6j, 14994j: a 10 000 kg airplane lands, descending a vertical distance of 10 km while travelling 100 km measured along the ground.
