Answer:

option A

12m/s

Step-by-step explanation:

Given in the question,

mass of object = 11kg

kinetic energy possess by = 792 joules

To find the velocity we use formula

v = $\sqrt{\frac{2KE}{m} }$

Plug values in the formula

v = $\sqrt{\frac{2(792)}{(11)} }$

v = $\sqrt{\frac{1584}{11} }$

v = $\sqrt{144}$

v= 12 m/s
