141443 When will a body of mass \(20 \mathrm{~kg}\) moving at 15 \(\mathrm{ms}^{-1}\), subjected to a retarding force of \(100 \mathrm{~N}\), come to rest?

141444 The acceleration at the end of \(2 \mathrm{~s}\), of a particle whose motion is represented by the equation \(s\) \(=4 t^{3}-8 t^{2}+5 t+4\) is

141446 A body of mass \(5 \mathrm{~kg}\) starts from the origin with an initial velocity \(u=30 \hat{i}+40 \hat{j} ~ m s^{-1}\). When a constant force \(F=-(\hat{\mathbf{i}}+\mathbf{5} \hat{\mathbf{j}}) \mathbf{N}\) acts on the body, the time in which the y-component of the velocity becomes zero is

141447 A bomb is dropped from an aeroplane flying horizontally with a velocity \(720 \mathrm{~km} / \mathrm{hr}\) at an altitude of \(980 \mathrm{~m}\). The bomb will hit the ground after a time.
