A car is moving with speed 30 m/sec on a circular path of radius 500 m . Its speed is increasing at the rate of 2m/s^{2}, What is the acceleration of the car
Text Solution
Verified by ExpertsThe correct answer is:
B
Net acceleration in nonuniform circular motion,
a \(= \sqrt{a_{t}^{2} + a_{c}^{2}}\) \(= \sqrt{(2)^2 + \left(\frac{900}{500}\right)^2} = 2.7 \, m/s^2\)
a_{t} = tangential acceleration
a_{c} = centripetal acceleration \(\overline{v^2} = \frac{\overline{v^2}}{r}\)
