141170 A balloon has mass of \(10 \mathrm{~g}\) in air. The air escapes from the balloon at a uniform rate with velocity \(4.5 \mathrm{~cm} / \mathrm{s}\). If the balloon shrinks in \(5 \mathrm{~s}\) completely. Then, the average force acting on that balloon will be (in dyne).
141171 At time \(t=0\) a particle starts travelling from a height \(7 \hat{z}\) in a plane keeping \(z\) coordinate constant. At any instant of time it's position along the \(x\) and \(y\) directions are defined as \(3 t\) and \(5 t^{3}\) respectively. At \(t=1 \mathrm{~s}\) acceleration of the particle will be
141172 The velocity of the bullet becomes one third after it penetrates \(4 \mathrm{~cm}\) in a wooden block. Assuming that bullet is facing a constant resistance during its motion in the block. The bullet stops completely after travelling at \((4+x)\) cm inside the block. The value of \(x\) is:
