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

Star appear in all sorts of sizes and colors...red, orange, yellow, blue, white. With all the colors that are there, why are there not any green stars? You would think there would be some right there beween the yellows and blues. I know the classifications have much to do with the surface temperature of a star, but yet no green stars.

Why?
