Abead of mass m = 5.0 kg is released from point a and slides on the frictionless track shown above. note that the bead slides, it doesn't roll, because there's no friction at all. (a) what is the total mechanical energy initially? - answer is 245 j (b) determine the bead's speed at point c? - answer is 7.67 m/s i have no clue how to solve this pls picture is attached!
