An object with the mass of 25g is rolling down a ramp with an inclination of 30˚ degrees off of the horizontal. The length of this ramp is 20 meters. There is another mass (10g) rolling down a ramp going the opposite direction, the inclination of this ramp is also 30˚, but the length is 30 meters (Assume this is going in the negative direction). We set them off at each other, and they collide inelastically.
a) What is the speed and direction of the combined mass?
b) What is the energy lost in this collision?
