Three identical blocks, A, B, and C, are on a horizontal frictionless table. The blocks are connected by strings of negligible mass, with block B between the other two blocks. If block C is pulled horizontally by a force of magnitude F = 49 N, find the tension in the string between blocks B and C.

Solutions

Expert Solution

For the system as a whole;
Fnet = 3*ma
=> 49 = 3*m*a
=> a = 49/(3m)


For block C;
49 - T = m*a
=> 49 - T = m*49/(3m)
=> T = 32.67 N

6. Solve parts a and b: A box is at rest on a horizontal, frictionless table. a. Horizontal force F1 points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 8 m/s2. Force F2 is also horizontal; it has magnitude 5.31F1 and acts at right angles to the direction of F1. If forces F1 and F2 act on the box at the same time, find the magnitude of the acceleration of...
