Question

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 1

If the magnitude of the force is 124

Step-by-step explanation:

F= 124

T= 62N

Mg a= 200 N Mg b= 100N

`a_(1)`= 0
`a_(2)`=0

`/a_(sys)/`=
`(EF)/(Mtot)`

=
`(+(20kg) (9.8M/s^(2) )- (10Kg)(9.8M/s^(2) ))/(30kg)`

= 3.2
`M/s^(2)`
