A racing car travels on a circular track ofradius 208 m. The car moves with a constantlinear speed of 26.3m/s.A) Find its angular speed. Answer in units of rad/s.

B) Find the magnitude of its acceleration. Answer in units of m/s^2.

Dear your question is under-progress, it would be available to you as soon as it completes within next few minutes.

Given: Linear speed v = 26.3 m/s, Radius r = 208 m The angular velocity is given by ω = dθ/dt = 26.3/208 = 0.126 rad/s.

acceleration?

Angular Acceleration = ω2r Angular Acceleration = (0.126)(2)(208) = 52.42 rad/s^2

Angular accelaration = r * linear accelaration

linear accelaration = 52.42 / 208 = 0.252 m/s^2

Acceleration is wrong

Is time given in question

no

linear acceleration = 0.00061m/s^2

angluar acceleration = 0.000061 x 208 = 0.1696 rad/s^2
