The masses of blocks A and B are 20kg and 10kg, 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 is applied to the pulley. Find the acceleration of block A and of block B if the magnitude of the force is

Answer:

If the magnitude of the force is 124

Explanation:

F= 124

T= 62N

Mg a= 200 N            Mg b= 100N

[tex]a_{1}[/tex]=  0                        [tex]a_{2}[/tex]=0

[tex]/a_{sys}/[/tex]=[tex]\frac{EF}{Mtot}[/tex]

= [tex]\frac{+(20kg) (9.8M/s^{2} )- (10Kg)(9.8M/s^{2} )}{30kg}[/tex]

= 3.2[tex]M/s^{2}[/tex]
