Question

What is the force when mass of one object is reduced 4 times (m/4) and the other object when increased 4 times (4 m)

Answer 1

Answer:

The formula of kinetic energy is KE=12mv2 , where KE is kinetic energy, m is the mass of the object, and v is the object’s velocity. So, if mass is halved and velocity is multiplied by 4, the formula becomes KE=12(m2)(4v)2 . Simplified this gives us that our new KE is equal to 4mv2 . Comparing this to the original kinetic energy we see that the final answer is: If mass is halved and velocity is quadrupled, kinetic energy is also multiplied by 8.
