268614 A vehicle is moving with uniform speed along horizontal, concave and convex surface roads. The surface on which, the normal reaction on the vehicle is maximum is

268672 A body of mass \(2 \mathrm{~kg}\) attached at one end of light string is rotated along a vertical circle of radius \(2 \mathrm{~m}\). If the string can withstand a maximum tension of \(140.6 \mathrm{~N}\), the maximum speed with which the stone can be rotated is

268673 A pilot of mass \(m\) can bear a maximum apparent weight 7 times of mg. The aeroplane is moving in a vertical circle. If the velocity of aeroplane is \(210 \mathrm{~m} / \mathrm{s}\) while diving up from the lowest point of vertical circle, then the minimum radius of vertical circle should be

268674 The length of a ballistic pendulum is \(1 \mathrm{~m}\) and mass of its block is \(0.98 \mathrm{~kg}\). A bullet of mass 20 gram strikes the block along horizontal direction and gets embedded in the block. If block + bullet completes vertical circle of radius \(1 \mathrm{~m}\), then the striking velocity of bullet is
