i have a distance time graph of a ball falling to the floor and bounce a couple of time and i worked out the velocity which was the gradient but i dont know how to work out the acceleration using the graph or data from it and another question reads "the balls gravitation potential energy is proportional to its highet, calculate the percentage loss in energy for each of the bounces? so i dont no that one either lol
if anyone could help with either thing i would greatly appreciate it

The velocity of a falling ball should increase as the ball falls. If you find the velocity at several points in time, and plot them, it should be a straight line and the slope will be the acceleration of gravity.
The potential energy of the ball at height h is mgh so the fraction energy loss will be the ratio of h's.

The slope of the line on a distance time graph is speed. in case you pick to locate speed you want to calculate its slope. If the line is thoroughly horizontal, then speed is 0.
