a) Find a general expression for mass m2 so that m1 will move at a constant speed up the ramp. Your answer will be based on (mu) and (theta).

b) Give a numerical value for (mu) and (theta) so that m2/m1 > 1

c) Give a numerical value for (mu) and (theta) so that m2/m1 < 1

Fg2 = m2g

Fg1x = m1gsin(theta)

Ff = (mu)Fn

Fn = Fg2y

a = 0m/s2

Fnet = ma

g = 9.8 m/s2

Fnet = Fg2 - Fg1x - Ff

0 = m2g - m1gsin(theta) - (mu)cos(theta)

m2g = m1gsin(theta) + (mu)cos(theta)

m2 = [m1gsin(theta) + (mu)cos(theta)] / g

My problem is that I don't understand how to give a numerical value for (mu) and (theta) so that m2/m1 > or < 1 without also determining the mass of either m1 or m2 since they are both a part of the general equation. Is it even possible without also giving a numerical value to one of the masses?? Any clarification is greatly appreciated.
