141675 A student is standing at a distance of 50 metres from the bus. As soon as the bus begins its motion with an acceleration of \(1 \mathrm{~m} / \mathrm{s}^{2}\), the student starts running towards the bus with a uniform velocity \(u\). Assuming the motion to be along a straight road, the minimum value of \(u\). So that the student is able to catch the bus is :
141676 From a balloon rising vertically upwards at 5 \(\mathrm{m} / \mathrm{s}\) a stone is thrown up at \(10 \mathrm{~m} / \mathrm{s}\) relative to the balloon. Its velocity with respect to ground after \(2 \mathrm{~s}\) is (assume \(\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}\) )
141677 The velocity of sound in a gas is \(1300 \mathrm{~m} / \mathrm{s}\) at STP and specific heat at constant pressure is \(6.84 \mathrm{cal} \mathrm{K}^{-1} \mathrm{~mol}^{-1}\). The rms velocity at STP is \(\left(\mathrm{R}=1.98 \mathrm{cal} \mathrm{K}^{-1} \mathrm{~mol}^{-1}\right.\) )
