Displacement of a particle is given by X equal to 20 + 10t² square calculate the instantaneous velocity t=2s
we are given thatX = 20 + 10t2 , x is the position of the object and t is the time.by Diffrenetiation , we will get the velocity i.e. dx/dt = Vdx/dt of 20 + 10t2 = 20tnow T= 4seconds (given in the qustion)20 x 2 += 40m/sanswer= 40m/s at t= 2 seconds
