**circle question its easy (still need help)**

Suppose you tie a rock to the end of a 1.5 m long string and spin it in a vertical circle. What is the minimum speed it can travel and "just" get around the top? (Hint: The rope will just start to go "slack" and the only force acting on the rock, downward, is gravity.)

-------m/s

here is my work:

so i thought it would be 9.9 since 9.8 is gravity or something i am completely lost. if someone could help that would be great
