What is the acceleration of the marble? Please, note that the curve passes through at

there is a distance time graph with a curved line and points at (0,0) , (4, 20) , (8,80)

Assuming that the acceleration of the marble is constant, its displacement at time t can be expressed using the SUVAT equation s = s0 + ut + (1/2)at^2. You can sub in the three given values of (t, s) to give you a set of equations that you can solve simultaneously for the three constants, one of which the acceleration “a”.
