The common difference if there is one is the constant difference that occurs between any term and the term before it.... in this case:
There is no common difference,
dx=18,20,16,18 the difference or velocity is not constant...
d2x=2, -4,2 the acceleration is not constant...
d3x=-6,6 the thrust is not constant
Now we might be tempted to say that:
d4x=12 and say that that is constant and we COULD make a quartic equation fit all the data points, but without further data points in the sequence there is no mathematical proof that the quartic equation would produce accurate data points outside of the range given...
And solving a system of five equations for five unknowns is tedious for such a problem...a^4+bx^3+cx^2+dx+e=y
Answer:
pp
Step-by-step explanation:
The ball's acceleration is the rate of change of its velocity, and its velocity is the rate of change of its height. So if is the ball's height at time , then
The ball is dropped from , and since it's being dropped there is no additional velocity added to it, so .
Integrating both sides of the ODE gives
and since , we have .
Integrating again gives
and since , we get
So the ball's height at any time is governed by
The ball hits the ground when :
