Since we know Mary's speed AND direction, we have
all the information we need to state her velocity.
Have them give up there phone for 15 minutes
talk to them when there in a good mood
watch a movie then have a disscution about it
It is in the noble gas group which has a full valence electron shell found in group 18
To find the horizontal distance multiple the horizontal velocity by the time. Since there is no given time it must be calculated using kinematic equation.
Y=Yo+Voyt+1/2at^2
0=.55+0+1/2(-9.8)t^2
-.55=-4.9t^2
sqrt(.55/4.9)=t
t=0.335 seconds
Horizontal distance
=0.335s*1.2m/s
=0.402 meters
