Question

PLEASE help with this question

Answer 1

option A

12m/s

Explanation:

Given in the question,

mass of object = 11kg

kinetic energy possess by = 792 joules

To find the velocity we use formula

v =
`\sqrt{(2KE)/(m) }`

Plug values in the formula

v =
`\sqrt{(2(792))/((11)) }`

v =
`\sqrt{(1584)/(11) }`

v =
`√(144)`

v= 12 m/s
