select the correct answer. whats the velocity of an 11 - kilogram object with 792 joules of kinetic energy? use $v = sqrt{\frac{2ke}{m}}$. a. 7 m/s b. 8 m/s c. 9 m/s d. 11 m/s e. 12 m/s

Answer

Explanation:

Step1: Identify given values

$m = 11$ kg, $KE=792$ J

Step2: Substitute values into formula

$v=\sqrt{\frac{2KE}{m}}=\sqrt{\frac{2\times792}{11}}$

Step3: Calculate numerator

$2\times792 = 1584$

Step4: Calculate fraction value

$\frac{1584}{11}=144$

Step5: Calculate square - root

$v=\sqrt{144}=12$ m/s

Answer:

E. 12 m/s
