A boy is on a sled moving down a hill at 20 m/s. The combined mass of the sled and child is 100 kg. The momentum of the child and sled is
A. 5 kg. m/s
B. 20 kg. m/s
C. 1000 kg. m/s
D. 2000 kg. m/s

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

its line 2 i just added the rest or else it wouldn't let me answer
