A car moving with speed 30 m/s on a circular path of radius 500 m . It speed is increasing at the rate of 2 $m / s^{2}$ . The acceleration of the car is at this instant is :-

Options:

Answer:

Solution:

$a_{t} = 2 m / s^{2}, a_{c} = \frac{v ^{2}}{R} = \frac{900}{500} = 1.8 m / s^{2}$ .

$∣ a ∣ = 4 + 3.24 = \frac{181}{5} \approx 2.7 m / s^{2}$ - (D).
