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

2. Margareth, driving at 40.0 m/s, enters a one-lane tunnel. She then observes a
slow-moving van 205 m ahead traveling at 6.00 m/s. Margareth applies her brakes
but can accelerate only at -2.50 m/s? because the road is wet. Will there be a
collision? State how you decide. If yes, determine how far into the tunnel and at
what time the collision occurs. If no, determine the distance of closest approach
between Margareth's car and the van.
