141714 The velocity of a body moving with uniform acceleration at a given instant of time ' \(t\) ' is 10 \(\mathrm{m} . \mathrm{s}^{-1}\). Five seconds later its velocity is \(20 \mathrm{~m} . \mathrm{s}^{-1}\). The distance travelled in that time is:

141715 A body moving with uniform acceleration describes \(12 \mathrm{~m}\) in the \(3 \mathrm{~s}\) of its motion and \(20 \mathrm{~m}\) in the \(5 \mathrm{~s}\). The velocity after \(10 \mathrm{~s}\) is

141716 A particle A moves along the line, \(y=30 \mathrm{~m}\) with a constant velocity, \(v\) parallel to \(x\)-axis. At the moment particle \(A\) passes the \(y\)-axis, a particle \(B\) starts from the origin with zero initial speed and a constant acceleration, \(a=\) \(0.40 \mathrm{~m} / \mathrm{sec}^{2}\). The angle between \(a\) and \(y\)-axis is \(60^{\circ}\). If the particles \(A\) and \(B\) collide after sometimes, then the value of \(|\mathbf{v}|\) will be
