Question

an object of mass 15 kg is moving with a uniform velocity of 4 kilometre per hour what is the kinetic energy possessed by the object ​

Answer 1

Answer:

We know that kinetic energy =

2

mv

2

So kinetic energy of given object = 120 J

Answer 2

ᴀɴsᴡᴇʀ :-

We know that kinetic energy =

$\frac{mv2}{2}$

So kinetic energy of given object = 120 ᴊ
