4 A student measures the time t for a ball to fall from rest through a vertical distance h. Knowing that
the equation h = gt2 applies, the student plots the graph shown.
Which of the following is an explanation for the intercept on the t axis?
A Air resistance has not been taken into account for larger values of h.
B There is a constant delay between starting the timer and releasing the ball.
C There is an error in the timer that consistently makes it run fast.
D The student should have plotted h against t 2.

The answer is D. Make a graph with position or velocity respect to time.

That's not true.  The only answer that would explain an intercept is B.  But you should also have posted the image for clarity.
