A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed. O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s

Explanation:

To find the speed given the kinetic energy and mass we use the formula

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

We have the final answer as

Hope this helps you

let that person have a turn to speak : )
