the kinetic energy of an object of mass m, moving with a velocity of 10m/s is 100 J. evaluate the kinetic energy of the same object when its velocity is doubled.
Clarified butter is milk fat rendered from butter to separate the milk solids and water from the butterfat. Typically, it is produced by melting butter and allowing the components to separate by density.

Answer:
Answer:
We know that
K.E = Kinetic energy attain by object
m = Mass of the object
v = Velocity of the object
Given parameters:
K.E. of the object = 25 J
Velocity of the object ( v) = 5 m/s
⇒

1st case:
When velocity is doubled, then
