1.	For particular bank road it's radius is 100 meterand the angle is 45 then find most safe speed.
Answer» FULL question: A CIRCULAR road of radius 1000 m has banking angle 45 o . The maximum safe speed of a car having mass 2000 KG will be, if coefficient of friction between TYRE and road is Answer 172m/s Explanation Given that: r=1000m,θ=45 0 ,μ=0.5,m=2000kg We know that maximum safe velocity for a banked is given by : v= 1−μtanθ rg(tanθ+μ) HENCE on putting the given values, we get v= 1−0.5tan45 1000×9.8×(tan45+0.5) or v=172m/s hence option A is correct

FULL question: A CIRCULAR road of radius 1000 m has banking angle 45

. The maximum safe speed of a car having mass 2000 KG will be, if coefficient of friction between TYRE and road is

Answer

172m/s

Explanation

Given that: r=1000m,θ=45

,μ=0.5,m=2000kg

We know that maximum safe velocity for a banked is given by :

1−μtanθ

rg(tanθ+μ)

HENCE on putting the given values, we get

1−0.5tan45

1000×9.8×(tan45+0.5)

or v=172m/s

hence option A is correct
