Q. A spring has a force constant of 909N/m and an unstretched length of 6cm. One end is attached to a post that is free to rotate in the center of a smooth table. The other end is attached to a 7 kg disk moving in uniform circular motion on the table, which stretches the spring by 4 cm. What is the centripetal force Fc on the disk? Answer in units of N.

Q. Heather and Jerry are standing on a bridge 51 above a river. Heather throws a rock straight down with a speed of 12. Jerry, at accurately the same instant of time, throws a rock straight up with the same speed. Ignore air resistance.
