difference in distance S= 30m-12m=18m.
initial velocity u=0, distance S=1/2at^2 at
a=2S/t^2=2×18/25=36/25=1.44m/s^2..having gotten the acceleration...we can get the velocity
using V^2=U^2+2aS . since u=0
v^2= 2×1.44×18=51.84
V=sqroot51.84
V=7.2m/s( that is the velocity)
Answer:
no
Step-by-step explanation:
she rounded differently on both of them

1.6
The average of this ten number is (1+6+2+4+4+3+5+5+2+8)/10=4
So the MAD is (|1-4|+|6-4|+|2-4|+|4-4|+|4-4|+|3-4|+|5-4|+|5-4|+|2-4|+|8-4|)/10
=(3+2+2+0+0+1+1+1+2+4)/10
=1.6
Answer: 200 divided by 4 = 50 so the answer should be 50 weeks.
