Click For Summary
To find the acceleration of two blocks, one on a frictionless surface and the other on a surface with friction, it's essential to account for all forces acting on each block. The initial attempt to calculate acceleration did not consider the frictional force acting on m2. A standard approach involves drawing Free Body Diagrams for each mass to identify forces and their relationships. The equations of motion must be set up using ΣF=ma for both blocks, incorporating the effects of gravity, friction, and any angles involved. Properly applying these principles will yield the correct acceleration formula for the system.
The answer is (B) but I don't really understand why.
Based on formula of Young Modulus:
$$x=\frac{FL}{AE}$$
The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A##
I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
