List of top Physics Questions on Momentum and Force

In the given figure, if the inclined plane and the pulley are frictionless, then the tension \(T\) in the string is

To drive a vertical nail of mass \(10\,\text{g}\) into wood through \(9\,\text{cm}\), an iron block of mass \(990\,\text{g}\) is dropped onto it freely from a height of \(10\,\text{m}\). If the collision between the nail and the block is perfectly inelastic, then the force of resistance offered by wood is \[ (g=10\,\text{m s}^{-2}) \]

When a force of 8 N is applied on a body, its velocity changes from 8 $ms^{-1}$ to $16~ms^{-1}$ in a time of 4 s. The force required to change the velocity of the same body from $16~ms^{-1}$ to $20~ms^{-1}$ in a time of 2 s is}
