Answer:
Yes
Explanation:
Non uniform acceleration is any acceleration that is not constant.
If you look at the graphs I have drawn in the above picture, the first two graphs shows a uniform acceleration.
The first graph is a positive acceleration, which means that the object is moving faster and faster at a constant rate. The second graph shows a deceleration, or negative acceleration, which means that the object is moving slower and slower at a constant rate.
For velocity- time graphs, acceleration can be seen by its gradient. So if the slope of the graph doesn't change, it has a uniform acceleration.
Graph 3 shows zero acceleration since the object is moving at a constant velocity (or speed). Thus, the object does not acceleration.
Graphs 4-7 shows a non uniform acceleration.
In graph 4, the object has a decreasing acceleration since the gradient of the graph is decreasing. This can be seen by the slope getting gentler and gentler.
Graph 5 shows an increasing deceleration, since the graph is getting steeper and steeper and the velocity is decreasing with time.
Graph 6: increasing acceleration
Graph 7: decreasing deceleration
The speed of an object in a mass-spring system is given under the function
Here,
m = mass
k = Spring constant
A = Amplitude
x = Position
When the position is at the equilibrium point (x = 0), the speed will be maximum, and could even be expressed as
So the correct answer is B.
