Answer:
0N
Step-by-step explanation:
Force = mass * acceleration
Given
Mass = 5kg
velocity = 19m/s
IF the velocity of the body is constant, then the acceleration will be zero.
Force = 5 * 0
Force = 0N
Hence the net force on the rock is 0N
Divide 14 2/5 by 6 to determine the number of pounds each person receives.
Convert 14 2/5 into an improper fraction: 72/5.
Divide 6 into 72/5; the result is 12/5, or 2 2/5 lb.
Each friend receives 2 2/5 lb of the pecans.

Answer:
The minimum of cows he needs are: 2
Step-by-step explanation:
There's a relation between each animal:
5 chickens equals 1 pig
3 pigs equals 2 sheep
5 sheep equals 2 cows
You can understand it as the following three abstractions:
5c = 1p (1)
3p = 2s (2)
5s = 2o (3)
Where:
c is for chickens
p is for pigs
s is for sheep
o is for cows
So now you have three equations with 4 variables. The next step is to obtain an equation that relates directly the variable c (chickens) with the variable o (cows). In order to do that from the equation 2 we obtain s in terms of p, as follow:
Then we replace s in the equation 3 and we obtain v in terms of p:
Now we replace v in the equation 1:
(4)
The equation 4 means that 1 chicken equals the fifteenth part of a cow. For this case the farmer needs 20 chikens, so we multiply per 20 each part of the equation 4:
As it is impossible to have 1.3333 cows, the answer is 2 cows approximately.
