Let's say you have a perfectly circular road around a point. A car is driving on this road and from above, the speed appears to be unchanging. The car is driving on this circular road without stopping.
a. Is the car moving at a constant speed?
b. Is the car moving at a constant velocity?
c. Is the car accelerating? (Going to need some explanation here)
d. Is acceleration constant?
Homework Answers
a) yes since speed is unchanging car is moving with constant speed
b) no since car is moving in a circle direction is changing continuously velocity is not constant
c) it is accelerating and that is towards center centripetal force should exist to allow a body to be in uniform circular motion since there is force there is acceleration towards center
d) a = v^2/r constant and towards center

A car is driving around a 700 foot radius - circular track with a centripetal acceleration of 1.07g (multiples of gravitation acceleration) at a speed of 47.7 m/s. If the car is now going at 3.0 m/s slower, at what maximum rate can the driver speed up by accelerating without causing a slide. I need help reaching the answer of 5.2 m/s.

A car is driving around a banked curve, with the road surface at an angle of 10.0º. If the radius of curvature of the road is 30.0 m and the coefficient of static friction between the tires of the car and the road is 0.65, what is the maximum speed (in km/hr) the car can go without skidding?
