371731 Two paper screens \(A\) and \(B\) are separated by \(150 \mathrm{~m}\). A bullet pierces \(A\) and then \(B\). The hole in \(B\) is \(15 \mathrm{~cm}\) below the hole in \(A\). If the bullet is travelling horizontally at the time of hitting \(A\), then the velocity of the bullet at \(A\) is: \(\left(g=10 \mathrm{~ms}^{-}\right.\) )
371732 A bullet of mass \(30 \mathrm{~g}\) moving with \(700 \mathrm{~ms}^{-1}\) collides with a block of mass \(4 \mathrm{~kg}\) hanging by a string of length \(0.4 \mathrm{~m}\). After collision, the block rises to a height of \(0.2 \mathrm{~m}\). Then find the velocity of the bullet when it comes out of the block
371734 The velocity of an object of mass \(2 \mathrm{~kg}\) is given by \(v=\left(8 t \hat{i}+3 t^{2} \hat{j}\right) m / s\), where \(t\) is time in seconds. What will be the direction of net force on the object relative to the positive direction of \(\mathrm{X}\)-axis, at the instant when its magnitude is 20N?
