A mass is thrown upwards with an initial velocity of 30m/s. A second mass is dropped from directly above, a height of 60m from the first mass 0.50s later. When do the masses meet and how hight is the point where they meet?

2 answers

They travel a combined 60m

distanceup+distancedown=60
30t-1/2 g t^2+0-1/2 g (t-.5)^2=60

solve it.
how am i supposed to solve it?
