List of top Physics Questions on Kinematics asked in JEE Advanced

A particle is thrown with a speed \(v\) from a point \(O\) at an angle \(\theta\) with the horizontal plane such that it passes through the point \(P\) at a height of \(1\,\text{m}\) and horizontal distance of \(5\,\text{m}\) from \(O\), as shown in the figure. If acceleration due to gravity is \(g\,\text{m s}^{-2}\), then the correct statement(s) is/are:

Consider a large disk of radius \(R\) and two smaller disks, each of radius \[ r=\frac{R}{50} \] lying on its circumference, as shown in the figure. The smaller disks are initially in contact with each other, with an angular separation \(\Delta\theta\) between their centers. They are made to roll without slipping in opposite directions, with constant angular velocities \(\omega\) and \(2\omega\) while the large disk is held stationary. The time at which the smaller disks are again in contact is: \[ \text{[Use }\sin(\Delta\theta)=\Delta\theta\text{ and ignore gravity.]} \]
