I have this ball that when OnClick needs to jump up 150px and down again. It need to do this in the total of 1 sec (1000ms).
I’ve tried a couple of methods. One dividing the time in two, first have going up and other half going down… but its somewhat unstable and not that smooth.
Anyone got a idea?

To figure out k, substitute (t, y) = (0.5, 150) and solve for k.
