- 2. A boy stands 10 m in front of a plane mirror . then be . . . - Socratic
Now,distance between the boy and his image is 7 +7 i e 14 meters So,the image moved to him by (20 −14) or 6 meters Alternatively, From the above discussion,clearly, v + u = x (let)= 2u So, x = 2u Or, dx dt = 2 du dt It means velocity of image should be twice than that of man's velocity,so if the man moves by 3m then the image will move to

- Question #05f5e - Socratic
The tension on cable is the sum of the man's and the elevator's weights Tension=G+ Gelevator When the elevator is accelerated downwards, there is an inertia force in the reverse direction This inertial force reduces the weight on the bathroom scale inertial force=691-499=299N Now ,let use the Newton's second law of motion F = m ⋅ a m:mass
