A racing car travels on a circular track of
radius 208 m. The car moves with a constantlinear speed of 26.3m/s.A) Find its angular speed. Answer in units of rad/s. (0.126 rad/s is the answer)
I need help finding B
B) Find the magnitude of its acceleration. Answer in units of m/s^2
Thank you for the opportunity to help you with your question!
A) C = 2π208=1307.072
now we can set up a ratio of the velocity to the distance and compare that to a unit circle
26.3/ 1307.072 = ω / 2π
cross multiply to find ω = 26.3(2π) / 1307.072
0.1264 rad/s ===> ANS
B)V²/R toward the center of the circle =26.3*26.3/208=3.3254m/s2
