Question: A roller coaster car is going over the top of a13-m-radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60% of their true weight.
Part I: How fast is the coaster moving?
I need expert help to solve the above question and express your answer to two significant figures and include the appropriate units.
