Consider two masses m1 and m2 at the top of two frictionless inclined planes. Both masses start from rest at the same height. However, the plane on which m1 site is at an angle of 30 degrees with the horizontal, while the plane on which m2 sits is at 60 degrees. If the masses are released, which is going faster at the bottom of its plane? Or are they both going at the same speed?
