Please answer the entire question, including the subquestions. This is one question, and according to the guidelines I can have two subquestions. Thank you!

1) A car is traveling at a constant speed of 22 m/s around a curve with a radius of 85 m. What is the car's acceleration? Then finish the question by answering the following two subquestions.
   
0 m/s2
   
22.0 m/s2
   
9.81 m/s2
   
5.69 m/s2

a)

What is the maximum speed that a 2200 kg car can go around a level circular track with a radius of 30.0 m without slipping if the coefficient of static friction between the tires and the road is 0.80?
   
10 m/s
   
15 m/s
   
27 m/s
   
66 m/s

b)

A 0.300 kg rock is rotating in a vertical plane on a 0.250 m long string. At the top of the path, the velocity is 4.00 m/s. Find the tension in the string at that point.
