Do you do this you will take 16×200 sandwich is 13 and 26 and then you take that and divided by 12:50 which is 1199 and take 1199 divided by the square root of 10 which will get you 1327
Answer:
The displacement is: - 80 i
Step-by-step explanation:
In order to answer the question, you have to apply the displacement formula, which is:
ΔX= Xf-Xi
Where ΔX is the displacement, Xf is the final position and Xi is the initial position. The formula represents the change in the position of an object from the origin.
Let the origin be in 0 km,with the x-axis positive to te right.
Notice that the displacement is a vector. The positions are:
Xf=163 km (i)
Xi= 243 km (i)
Because John starts in 243 km and finishes in 163 km.
Where i is the unit vector in the x direction.
Therefore:
ΔX= 163 i - 243 i
Solving:
ΔX= -80 i
Notice that for calculating the displacement you just need the initial and final position. It doesn't depend on the distance traveled.
That would be zero becuase there are 4 quarts ina gallon and 8 pnts and 16 ounces
7/1 x 3/14 = 21/14 = 3/2 = 1 1/2
The answer is 1 1/12 or 1.5, but I recommend the fraction way since the problem was in fractions!
