A racing car completes 5 rounds of a circular track in 2 minutes. Find the radius of the track if the car has uniform centripetal
Given: 5 rounds = 2πr(5), t = 2minutes = 120s To find: Radius (r) Formula: acp = ω2r Calculation: From formula, acp = ω2r ∴ π2 = \(\frac{V^2}{r}\) But v = \(\frac{2\pi r(5)}{t}=\frac{10\pi r}{t}\) ∴ π2 = \(\frac{100 \pi^2 r^2}{rt^2}\) ∴ r = \(\frac{120\times120}{100}\) =144m The radius of...
