A 0.50 kg ball attached to the end of a horizontal cord is rotated in a circle radius 2.1m on a frictionless horizontal surface. If the cord will break when the tension in it exceeds 80 N, what is the maximum speed the ball can have? Express your answer to two significant figures and include the appropriate units.

In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for the rockets position measured from the center of the Earth is given by y(t)=(R3/2+3g2Rt)2/3j where R is the radius of the Earth (6.38 106 m) and g is the constant acceleration of an object in free fall near the Earths surface (9.81 m/s2). a. Derive expressions for vy(t) and ay(t). b. Plot y(t), vy(t), and ay(t). (A spreadsheet program would be helpful.) c. When will the rocket be at y=4R? d. What are vy and ay when y=4R?
