List of top Physics Questions asked in JEE Main

A car is moving with a uniform speed of $72km/h$. After applying brakes it stops after traveling $100m$ distance. If its mass along with the passengers is $1000kg$, then the value of force due to the application of brakes will be in newton:

The equation of motion of system is given by $m\ddot{x}+c\dot{x}+kx=0$. The damped vibration, ${\omega }_d$ can be written as:
