The graph to the right is a plot of position versus time. For which labeled region is the velocity positive and the acceleration negative? A. aB. bC. cD. d |

Answer» Correct Answer - D For d slope `dx//dt` is `+ve`, so velocity is `+ve` But `(d.((dx)/(dt)))/(dt)` is -vebecause slope decreasing so `(d.((dx)/(dt)))/(dt)= (d^(2)x)/(dt^(2))` is -ve, therefore acceleration is -ve |
