Kinematics Question 748

Question: Find the maximum velocity for skidding for a car moved on a circular track of radius 100 m. The coefficient of friction between the road and tyre it’s 0.2 [CPMT 1996; Pb. PMT 2001]

Options:

A) 0.14 m/s

B)140 m/s

C) 1.4 km/s

D)14 m/s

Show Answer

Answer:

Correct Answer: D

Solution:

$ {v _{\max }}=\sqrt{\mu rg}=\sqrt{0.2\times 100\times 9.8}=14m/s $
