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. The centripetal force acting on the vehicle is: (a) 560 N (b) 14 N (c) 2800 N (d) 2240 N

Answer: (a). F = mω² r F = 200 × (0.2)² × 70 = 200 × 0.04 × 70 F = 560 N So the answer is (a) 560 N.

Centripetal Acceleration & Force

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

Show answer and solution

Answer: (a)

$F = m\omega^2 r$
$F = 200 \times (0.2)^2 \times 70 = 200 \times 0.04 \times 70$
$F = 560\text{ N}$
So the answer is (a) $560\text{ N}$ .
