371667 A cricket ball of mass \(0.5 \mathrm{~kg}\) strikes a cricket bat normally with a velocity of \(20 \mathrm{~m} \mathrm{~s}^{-1}\) and rebounds with a velocity of \(10 \mathrm{~m} \mathrm{~s}^{-1}\). The impulse of the force exerted by the ball on the bat is

371668 The rate of mass of the gas emitted from rear of a rocket is initially \(0.1 \mathrm{~kg} / \mathrm{sec}\). If the speed of the gas relative to the rocket is \(50 \mathrm{~m} / \mathrm{sec}\) and mass of the rocket is \(\mathbf{2} \mathbf{~ k g}\), then the acceleration of the rocket in \(\mathrm{m} / \mathrm{sec}^{2}\) is
