This problem doesn't make sense to me.  The ball isn't accelerating if it has a constant velocity...

can you make a guess?

do you have any more instructions?

anonymous · Answer

i don't think there is enough info...

whpalmer4 · Answer

Well, 20 m/s^2 * 0.75 s = 15 m/s, so that's a plausible answer, but I agree there isn't enough info here to actually work it out properly
