Mass is not a factor in this problem; ignore it.

Like the last problem - find how long it took to hit the ground - use the same formula as last time.

then use distance = speed*time again, this time you know distance, time but not speed.

^distance will be horizontal distance.

h=0.5gt^2 will find time, h is vertical height.
