Answer: E =172.932 μm
Step-by-step solution:
When E is located at point (-40, -20)
According to Pythagoras’ theory, the displacement of E from its point of origin = √(40² + 20²) = 44.721 μm.
Total distance travelled = AB + BC + CD + DE.
Using Pythagoras’ theorem again,
AB = √(100 + 2500) = 50.9902 μm
BC = 10 μm
CD = √(100 + 1600) = 41.231 μm
DE = √(2500 + 2500) = 70.7107 um
Total displacement of E =172.932 μm
