# A Vehicle is Moving on a Circular Track Whose Surface is Inclined Towards the Horizon at an Angle of 10°. the Maximum Velocity with Which It Can Move Safely is 36 Km / Hr. Calculate the Length of the Circular Track - HSC Science (General) 12th Board Exam - Physics

#### Question

A vehicle is moving on a circular track whose surface is inclined towards the horizon at an angle of 10°. The maximum velocity with which it can move safely is 36 km / hr. Calculate the length of the circular track. [π = 3.142]

#### Solution

Given v=36kmh^-1=36xx5/18=10m/s, theta=10^@

To Find: Length of circular track s(l)

formulae: r=(v_max^2)/(g tan theta)

r=(10^2)/(9.8xxtan 10^@)

=57.88 m

l=2piR=2xx3.14xx57.88=363.48m

The length of the circular track is 363.48 m.
