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

25) A 0.50 kg mass attached to the end of a string swings in
a vertical circle (radius = 2.0 m). When the string makes an
angle of 30 degrees with the vertical, the speed of the mass
is 8.0 m/sec. What is the magnitude of the force of the
string on the mass at this position?

A Formula One race car with mass 750.0 kg is speeding through a course in Monaco and enters a circular turn at 220.0 km/h in the counterclockwise direction about the origin of the circle.

If the radius of curvature of the first turn is 130.0 m and that of the second is 100.0 m, compare the angular momenta of the race car in each turn taken about the origin of the circular turn.
