A vehicle of mass $200 kg$ is moving along a levelled curved road of radius $70 m$ with angular velocity of $0.2 rad s^{- 1}$ . The centripetal force acting on the vehicle is:

Options:

Answer:

Solution:

The centripetal force is given by
$F = \frac{M v^{2}}{R} = M R ω^{2}$
The given data is
$M = 200 kg R = 70 m ω = 0.2 rad s^{- 1}$
The magnitude of the force is
$F = 200 \times 70 \times 0 . 2^{2} N$
$\Rightarrow F = 560 N$
