Question:medium
A car is moving with velocity V at the top of a semi-circular hill of radius 40 m such that the normal force on it is zero. Find the velocity (V) of the car. [use $g = 10\ ms^{-2}$]
A car is moving with velocity V at the top of a semi-circular hill of radius 40 m such that the normal force on it is zero. Find the velocity (V) of the car. [use $g = 10\ ms^{-2}$]
Show Hint
For $N=0$ at the top of a hill, Critical Velocity $v = \sqrt{gR}$.
