A particle moves along a straight line such that distance x traversed in t seconds is given by x = t2(t + 1), the acceleration of the particle, will be-A-3t3 2tB-3t2 + 2tC-6t 2D-6t + 2E-3t 2-D-6t + 2

Question

APTITUDE CRACK · Accepted Answer

D 6t + 2 x=t^2(t+1)=t^3+t^2. Differentiating on both side w.r.t. t =&gt; dx/dt=3t^2+2t then double differentiation: d^2x/dt^2=6t+2. x = t2(t+1). x = t3+t2. dx/dt = 3t2+2t. d2x/dt2 = 6t+2. This is the required answer of the acceleration but acceleration negative sign indicated.
