Given v is not 0, m is not 0 and t is not 0
We need to find the sign of
v^2*m^3 / t^4
We can see that all we need to determine is the sign of m since v and t when squared and when taken to the power 4 are alwasys positive.
Stmt I
m> v^2
v^2 is always positive so m is positive therefore v^2*m^3 / t^4 > 0
SUFF
Stmt II
m> t^4
t^4 is always positive so m is positive therefore v^2*m^3 / t^4 > 0
SUFF
