Question

The masses of blocks A and B in the figure (Figure 1) are 20.0 kg and 10.0 kg, respectively. The blocks are initially at rest on the floor and are connected by a massless string passing over a massless and frictionless pulley. An upward force F⃗ is applied to the pulley.

Find the acceleration  a⃗ 

A  of block A when F is 124 N .

Answer 1

You are given the masses of blocks A and B in the figure are 20.0 kg and 10.0 kg, respectively. The blocks are initially at rest on the floor and are connected by a massless string passing over a massless and frictionless pulley. An upward force F⃗ is applied to the pulley. The acceleration is 4.13 m/s^2.
