Expert Solution

Three identical blocks connected by ideal strings are being pulled along a horizontal frictionless surface by a horizontal force F.

The magnitude of the tension in the string between blocks B and C is Tbc= 3.00N .

Assume that each block has mass m= 0.400kg.

The force, F, is causing all 3 blocks to accelerate at the same rate. The tension in the string between blocks B and C is caused by the horizontal force, F, which is pulling all 3 blocks.

The string between blocks B and C is pulling blocks B and A.

The 3.00 N force is causing the mass of B + A to accelerate.

F = m * a
3.00 =( 0.400+0.400) * a
Acceleration = 3.00 ÷*( 0.800) = 3.75 m/s^2
This is the acceleration of all 3 blocks is 3.75

The horizontal force, F =MASS *ACCELERATION

F = (mass of 3 blocks = Ma+Mb+Mc) * 3.75

F = 1.2 * 3.75 = 4.5 N

force F = 4.5N

T(AB) is only pulling block A.
T(AB) = m*f

tension ab = 0.4 * 3.75 = 1.5 N

Tab = 1.5 N
so the tension and the forces are calculated
