A 944-kg automobile rounds a curve at a constant speed of 35 m/s, undergoing an acceleration of magnitude 1.9 m/s2 as it proceeds.   What is the radius of the curve?  (Answer in m.)

A particle traveling in a circular path of radius 300 m has an instantaneous velocity of 30 m/s and its velocity is increasing at a constant rate of 4 m/s2. What is the magnitude of its total acceleration at this instant?

A person drives a car around a circular cloverleaf with a radius of 80 m at a uniform speed of 10 m/s.  what is the acceleration of the car?  comapre this answer with the acceleration due to gravity as a percentage.

To withstand "g-forces" of up to 10 g's, caused by suddenly pulling out of a steep dive, fighter jet pilots train on a "human centrifuge." 10 g's is an acceleration of 98 m/s². If the length of the centrifuge arm is 15.0 m, at what speed is the rider moving when she experiences 10 g's? Express your answer with the appropriate units.
