141314 Particle \(\mathbf{A}\) moves along \(\mathrm{X}\)-axis with a uniform velocity of magnitude \(10 \mathrm{~m} / \mathrm{s}\). Particle \(B\) moves with uniform velocity \(20 \mathrm{~m} / \mathrm{s}\) along a direction making an angle of \(60^{\circ}\) with the positive direction of \(\mathrm{X}\)-axis as shown in the figure. The relative velocity of \(B\) with respect to that of \(A\) is

141315 A particle moves along \(x\)-axis and its displacement at any time is given by \(x(t)=2 t^{3}-\) \(3 t^{2}+4 t\) in SI units. The velocity of the particle when its acceleration is zero, is

141316 A shell of mass \(5 \mathrm{M}\), acted upon by no external force and initially at rest, bursts into three fragments of masses \(M, 2 M\) and \(2 M\) respectively. The first two fragments move in opposite directions with velocities of magnitudes \(2 v\) and \(v\) respectively. The third fragment will

141317 The velocity of a car travelling on a straight road is \(36 \mathrm{kmh}^{-1}\) at an instant of time. Now travelling with uniform acceleration for \(10 \mathrm{~s}\), the velocity becomes exactly double. If the wheel radius of the car is \(25 \mathrm{~cm}\), then which of the following is the closest to the number of revolutions that the wheel makes during this 10 s?
