362158 On turning a corner, a motorist rushing at \(40\;m{\rm{/}}s\), finds a child on the road \(108\;m\) ahead. He instantly stops the engine and applies the brakes so as to stop it within \(1\;m\) of the child, what time is required to stop it?

362159 A particle moves along the \(X\) - axis. The position \(x\) of a particle w.r.t time from origin given by \(x=b_{0}+b_{1} t+b_{2} t^{2}\). The acceleration of particle is

362160 The motion of a particle along a straight line is described by equation \(x = 8 + 12t - {t^3},\) where, \(x\) is in metre and \(t\) in sec. The retardation of the particle when its velocity becomes zero, is

362161 A particle moves along a straight line such that its displacement at any point time \(t\) is given by \(s = 3{t^3} + 7{t^2} + 14t + 5\). The acceleration of the particle at \(t = 1\,s\) is
