A position-time graph is shown below:
1 answer:
Answer: The object moves forward at 5 m/s, stops, and then changes velocity.
Explanation:
With the information given in the question we can graph the points (image attached).
As we can observe, in the first segment of the graph the velocity is increasing linearly (at a constant rate) and is 5 m/s, then in the second segment we can see the position of the object remains the same from second 2 to second 4, which means the object is stopped.
Finally, in the third and last segment, we can observe a change in velocity (at a negative constant rate, because is decreasing), which is decreasing until the object stops.

Answer:
Explanation:
given,
Speed of a wave on violin A = 288 m/s
Speed on the G string = 128 m/s
Force at the end of string G = 110 N
Force at the end of string A = 350 N
the ratio of mass per unit length of the strings (A/G). = ?
speed for string A
.......(1)
speed for string G
........(2)
Assuming force is same in both the string
now,
dividing equation (2)/(1)
