141408 A person is running with an uniform velocity towards a flyover. He takes \(5 \mathrm{~s}\) to reach the flyover from a reference point and takes \(50 \mathrm{~s}\) to cross the flyover from the same reference point. If the length of the flyover is \(1000 \mathrm{~m}\) then his velocity in nearly
141409 Two particles \(A\) and \(B\) are moving along positive \(x\)-and positive \(y\)-axes respectively with the same speed \(\mathrm{v} \mathrm{m} \mathrm{s}^{-1}\). At \(\mathrm{t}=0\), they both pass through the origin. The equation of the straight line joining \(A\) and \(B\) at time \(t\) is
141410 A truck carrying sand having a total mass of \(1600 \mathrm{~kg}\) is moving with a uniform velocity of 15 \(\mathrm{ms}^{-1}\). Sand is dropped into it at a rate of \(24 \mathrm{~kg}\) \(\min ^{-1}\). The force needed to keep the truck moving with uniform velocity is
141411 A passenger saw a bus standing 10 meters ahead of him. The bus started moving with a constant acceleration \(5 \mathrm{~ms}^{-2}\) away from him. To catch the bus the passenger ran at constant speed towards the bus. The minimum speed of the passenger to catch the bus is
