A car is moving with speed \(30 \mathrm{~ms}^{-1}\) on a circular path of radius \(500 \mathrm{~m}\). Its speed is increasing at a rate of \(2 \mathrm{~ms}^{-2}\), what is the acceleration of the car?

  1. A \(2 \mathrm{~ms}^{-2}\)
  2. B \(2.7 \mathrm{~ms}^{-2}\)
  3. C \(1.82 \mathrm{~ms}^{-2}\)
  4. D \(9.82 \mathrm{~ms}^{-2}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2.7 \mathrm{~ms}^{-2}\)

Step-by-step Solution

Detailed explanation

Net acceleration in non-uniform circular motion,
\(=\sqrt{(2)^{2}+\left[\frac{900}{500}\right]^{2}}=2.7 \mathrm{~ms}^{-2}\)
