if we mark the three lines on inclined plane at some distance and note down the time at which it passes through this line we can find the acceleration. Initially the velocity of the sphere is zero(at first line) when it passes through the 2nd line note this time and measure the distance between first line and second line then find the velovity by using the equation
similarly measure the distance between second and third line and note the time taken by the sphere to reach third line. now find the velocity of this portion.
now you have two velocity one of first portion and one of 2nd portion, now you can find the acceleration using equation
