Find how fast is the coaster moving

Reference no: EM13716825

Question: A roller coaster car is going over the top of a 12-m-radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60% of their true weight.

Question 1: How fast is the coaster moving?

I need help to determine how fast the coaster is moving.
