3. Mass M = 3.00 kg slides 'om rest without friction down the ramp of length L = 10.0 m as seen in the diagram (not to scale). At the bottom it strikes mass m = 1.25 kg and the two lock together and move up the frictionless circular arc. (Please work symbolically as far as you can, plugging in numbers later in each part.) 1's; t. a) Calculate the speed of M at the bottom of the incline (upon reaching the at ground), VB using Work and Energy techniques. b) Calculate the speed of the combined system of masses just after the collision, V'. c) Is this collision elastic, inelastic or perfectly inelastic? (1) Calculate the nonconservative work done during the collision of the two masses. e) As the masses move together around the circular arc and reach the half way spot (at the 3:00 position as on a clock), what force(s) provides the centripetal force? f) The radius of the arc is 3.50 m. Calculate the speed of the combined system when they are half way up the arc (at the 3:00 position as on a clock). g) At this same position, calculate the normal force acting on the system
