A racing car travels on a circular track of
radius 208 m. The car moves with a constant
linear speed of 26.3m/s.

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

acceleration?

Jun 23rd, 2015

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

Jun 23rd, 2015

no

Jun 23rd, 2015

linear acceleration = 0.00061m/s^2

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