Answer:
a) 12/11  m/sec²
b) 14/11  m/sec²
Explanation:
Since the direction of where the cable connects from is not given, it is assumed the block lies on horizontal ground and is being pulled from the right side by the cable.
Using the equation [tex]Force= Mass * Acceleration[/tex] and plugging in the values we get
[tex]12=11 * Acceleration[/tex]
and
[tex]14=11*Acceleration[/tex]
Solving for both we get the answers stated above.
