heyy, i have question abt position-time graph, i can't draw it so i'll try to explain it, it looks like an upside prabola, and the question asks first for the average velocity in certain time interval; i knew how to do that by subtracting xf-xi/tf-ti.
but then another branch of te question is to determine the instantaneous velocity at t=2 by measuring the slope of the tangent ?
how do u find the slope at a certain second ??
and another brach is at what value of t is the velocity zero ??
