Think about the formula for potential energy. (Surely you remember it):
Potential energy = (mass) x (acceleration of gravity) x (height)
-- The mass on the end of the pendulum doesn't change.
-- The acceleration of gravity doesn't change.
-- The only thing that changes is the height of the mass on the end.
So the potential energy is lowest when its height is the lowest.
That's position <em>B </em>.
Answer:
v(t) = 27 units
Explanation:
The function s(t) represents the position of an object at time t moving along a line such that,
and
We need to find the average velocity of the object over the interval of time [2,6]. The velocity of the object is equal to the total distance divided by time. It is given by :
v(t) = 27 units
So, the average velocity of the object is 27 units. Hence, this is the required solution.
In general, pitch increases more rapidly than frequency for tones below 1000 Hz and less rapidly for tones above 1000 Hz. That is, for frequencies above 1000 Hz a greater change in frequency is needed to produce a corresponding change in pitch.
Answer:
The answer is 80 m/s
Explanation:
You divide 240 by 3 since your force is 240N, then 3 is your mass, so divide and get 80
A = v1-v0/t so v1= a*t (v0 is o m/s) v1=
20m/s * 60 s = 1200 m/s
