The answer is either harmonic motion or simple harmonic motion.
Answer:
The maximum potential energy of the net, compared to its unstretched potential energy, is:
Explanation:
From the question we are told that
The weight of the man is
The distance of the window to the net is
The distance stretched by net is
Generally from the of conservation energy , the total energy is conserved
This implies that
Where is the initial potential energy of the , man which is mathematically evaluated as
Substituting values
And is the unstretched potential energy of the net
And is the final potential energy of the man which is mathematically evaluated as
Substituting values
The negative show that the direction of the man is against the direction of gravitational pull
And is the maximum potential energy of the net when stretched
So the above equation becomes
So
Sorry I honestly don’t know that answer
Answer:
This graph shows the distance moved by the train with respect to time
Between t = 3 to t = 5 the train is at rest
Since this graph shows the distance covered by the train so it is a scalar quantity
Explanation:
Here from the graph we can see the distance covered by the train with respect to time
So here from the slope of this graph we can find the speed of the train
Also from t = 3 to t = 5 we can see that slope of the graph is zero
So here n this time interval there is no motion or it is at rest
Now since we know that this is distance vs time graph so it is a scalar quantity showing in this graph

<span>a) Work = force x distance = 5.0 x 10^5 x 509 = 2.54 x 10^8
b) no change in velocity, therefore KE = 0
c) KE = 31 J
d) v = 15 m/s</span>
