Question
hello can you please show the steps and the answers of each step so i can figure out where the numbers come from/ thank you. A mass m1 = 5.7 kg rests on a frictionless table and connected by a massless string to another mass m2 = 3.9 kg. A force of magnitude F = 37.0 N pulls m1 to the left a distance d = 0.77 m. The work done by the force F on the two block system is 28.49J and the work done by the normal force on m1 and m2 is 0 J . the final speed of the two blocks is 2.44 m/s and the work done by the tension (in-between the blocks) on block m2 is 11.61 J . 6) The net work done by all the forces acting on m1 is positive. 5) What is the tension in the string in N and and what is the NET work done on m1?Explanation / Answer
Speed of both block is 2.44 m/s
Work done by tension =11.61 J
(5)
Work done by tension is also given as:
T*0.77 = 11.61
T = 15.078 N
Net work done on m1:
W(net) = -15.078*0.77+37*0.77 = 16.88 J [Work done by tension is negative as it is opposite to F ]
