141328 A trolley of mass \(20 \mathrm{~kg}\) carries \(5 \mathrm{~kg}\) grain and moves on a horizontal, smooth and straight track at \(20 \mathrm{~ms}^{-1}\). If the grain starts leaking out of a hole at the bottom at time \(t=0\), at rate 0.2 \(\mathrm{kgs}^{-1}\), the speed of the trolley at \(t=10 \mathrm{~s}\) will be nearest to

141329 The displacement of a body is given by \(3 \mathrm{~s}=\mathrm{a}+\) \(4 b t^{3}\), where \(a\) and \(b\) are constants. What is the velocity of the body at the end of \(1 \mathrm{~s}\) ?
