Question
The combined mass of a race car and its driver is 600. kilograms. Traveling at a constant speed, the car completes one lap around a circular track of radius 160 meters in 36 seconds.
A) Based on the given information, calculate the speed of the car.
B) Calculate the magnitude of the centripetal acceleration of the car in the given diagram.
Please show all work.

a. speed=distance/time= 2PI*radius/time
b. centripetal acc= speed^2/radius
b. centripetal acc= speed^2/radius

a. speed=distance/time= 2PI*radius/time
What does 2PI mean?

Speed :
Circumference is 2pi(r)
So C= 1005
Speed:
Distance/time
1005/36= 27.93 m/s^2
Circumference is 2pi(r)
So C= 1005
Speed:
Distance/time
1005/36= 27.93 m/s^2

just do 2pi(radius)/t
circumference for distance
d/t so d=circumference

circumference for distance
d/t so d=circumference
