A We can observe independently vertical component of arrows speed. Since there isn't vertical speed at start we can observe this case as free fall where formula for traveled distance is:
h = 1/2*g*t^2
we can express t
t = √2h/g
t = 1,427s
after 1.427 seconds in air arrow will hit ground.
B. The range we get simply by calculating how much distance will arrow travel in 1.427 seconds at speed of 64.5m/s. speed is not changing because we are ignoring air resistance.
s = t*v = 93.468m
Answer:
Option B.
Step-by-step explanation:
Eric states the applied interest is simple interest. We need to check whether the this statement is true or false.
In simple interest, the amount of deposit increased at a constant rate. It means the difference between future values of any two consecutive years will same.
Difference between future values of first two years.

Difference between future values of 2nd and 3rd year is

Since d₁≠d₂, therefore, the given statement is false.
Thus, the correct option is B.
Answer: 12
Step-by-step explanation:
It isn't. It's on the y-axis. The requirement for a point to be on an axis is if both x and y are not equal to 0.
