PHY 101 Circular Motion Objective Question

Question

For a car negotiating a flat curve, the maximum speed without sliding is derived from which relationship?
Options
A v = μgr
B v² = μgr
C μg = v²/r
Correct Answer
D μ = v²/gr
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture shows the derivation: μmg = mv²/r, which simplifies to μg = v²/r. This gives the relationship for the maximum speed.

Hint

The derivation cancels the mass from both sides of the equation F_friction = F_centripetal.
