Q1. A 2.62 kg mass attached to a light string rotates on the horizontal, frictionless table. The radius of the circle is 0.4207 m, and string can support a mass of 14.70 kg before breaking.

The acceleration of gravity is 9.80 m/s2.

What maximum speed can the mass have before the string breaks?

Q2. An object is dropped from an altitude of 1.10R above Earth's surface. Where R is the radius of the earth. What would be the speed of the object just before it hits Earth?
