Question
Use the following situations to answer questions 34-36. Four boxes are traveling to the left with the same velocity, when they are acted upon a horizontal force along a inctionless surface, the magnitude of the forces and the displacement they caused are given, as well as, the mass of the objects. Please see figures below. d=3m d 4m F= 100 N 2 m 34. Rank the change in kinetic energy for each box from smallest to largest. 35. Rank the final kinetic energy for each box from smallest to largest. a. 36. Rank the final speed of each box from smallest to largest.Explanation / Answer
34.
the change in kinetiç energy is equal to the work done.
dKA = Fd = 75*4 = 300 J
dKB = Fd = 75*4 = 300 J
dKC = Fd = 50*6 = 300 J
dKD = Fd = 100*3 = 300 J
Option c is correct answer.
