Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

A car traveling at 20 m/s rounds a curve so that its centripetal acceleration is 5 m/s^2.
What is the radius of the curve?

a. 8 meters

b. 4 meters

c. 80 meters

d. 160 meters
