A body of mass \(2\) kg is moving with a momentum of \(10\ \text{kg m s}^{-1}\). The force needed to increase its kinetic energy four times in \(10\) seconds is
Show Hint
If kinetic energy becomes four times, speed becomes twice, because \(K\propto v^2\).

Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Knowing the initial position \( x_0 \) and initial momentum \( p_0 \) is enough to determine the position and momentum at any time \( t \) for a simple harmonic motion with a given angular frequency \( \omega \).
Reason (R): The amplitude and phase can be expressed in terms of \( x_0 \) and \( p_0 \).
