Which Of The Following Desribes A Displacement Vs Time Graph That Looks Like This Time A Constant Nonzero Acceleration B Increasing Velocity C Constant Velocity class=

Sagot :

It would a constant non-zero acceleration because acceleration (the second derivative of position) is what determines concavity, and if it is positive, the graph of position/displacement will be concave UP. The acceleration is constant, so velocity is increasing at a constant rate. Therefore, position would be increasing at an exponential rate.
