Consider the equation K = (mv^2)/2.
If v and m are both doubled, by what factor is K increased?	Choose the correct choice:
A) 2 B) 6 C) 8 D) 10 E) 4
We have,   K = (mv^2)/2   On doubling both m and v,   K = [(2m)*(2v)^2]/2   K = (2m*4v^2)/2   K = (8mv^2)/2   K = 8*(mv^2)/2   Initially K = (mv^2)/2. After changing m and v, K = 8*(mv^2)/2   Hence, K increases by 8 times.   Answer = 8 = 8
