A kid plays with a yo-yo of mass 125 g and twirls it in a vertical circle. The lneght of the string is 90.0 cm. The kid twirls it just fast enough to keep it moving in a complete circle, results in a centripetal acceleration of 5.00 g at the lowest point. Find the speed of the yoyo at the highest point, lowest point, and tensions.
