If two rocks are dropped from a resting position and then both achieve a velocity of 35 m/s in 3.5 seconds, what is their acceleration? hel

i think it would be 5

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
