Question

Use the graph to answer the question. Study the graph.

Which of the following statements is true about this graph?
A. An object is accelerating
B. An object is traveling at a constant velocity
C. An object is in free fall

Answer 1

Oh darn.... I need to get my old kinematics notes.

Answer 2

An acid may be defined as
A. a substance that accepts protons
B. a substance that donates protons
C. a substance that forms hydroxide ions

Answer 3

s(t) is the location function
v(t) is the velocity ​​function.
a(t) is the acceleration function.


_______


v(t)=s'(t) so the tangent is the velocity to a (s,t) graph.
a(t)=v'(t)=s''(t)

Motion with constant acceleration would look like a quadratic function on a (s,t) graph becuase we can write the equation as the following:
\[s(t)=\frac{ 1 }{ 2 }a _{0}*t+v _{0}*t+s _{0}\]

Motion with constant velocity is given by the following equation and would give a right line:
\[s(t)=v _{0}*t+s _{0}\]

Answer 4

i already got the first question done

Answer 5

Aha.

Answer 6

Can you define a acid then (Brøndsted acid)?

Answer 7

im a redneck from the great states of america and i still got it done before you could write all that pellet

Answer 8

Lol what is that supose to mean?

Answer 9

Beside, what I do is to explain theory... If I wanted to give a stright answer I could.
