Answer to Question #768 in Mechanics | Relativity for brian
Two blocks connected by a string are pulled
across a rough horizontal surface by a force
applied to one of the blocks, as shown.
The acceleration of gravity is 9.8 m/s2
If each block has an acceleration of 2.5 m/s2
to the right, what is the magnitude of the
Answer in units of N.
There are the force of friction (μ* m *g) and the tension of the string T acting on each block acts. For the first block the equation of the forces would be: F- T - μ* m *g = ma for the second block: T - μ * m *g = ma
F - 2 μ * m *g = 2 ma F = 2m (a + μ*g).
So for the completion of this question we have to know the coefficient of friction and the mass of blocks.
