Answer:
The needed force is 400 N.
Explanation:
We need to calculate the force for 1.00 m string
According to graph,
The force applied for stretch from 0.10 to 0.15 is 20 N.
0.10-0.15 = 0.05 m
So, the force applied is 20 N for 0.05 m.
For stretch 0.05 m = 20 N
For stretch 1 m =
Hence, The needed force is 400 N.

Answer:
(a):
(b):
(c):
(d):
(e):
Explanation:
Given, the position of the particle along the x axis is
The units of terms and
should also be same as that of x, i.e., meters.
The unit of t is seconds.
(a):
Unit of
Therefore, unit of
(b):
Unit of
Therefore, unit of
(c):
The velocity v and the position x of a particle are related as
(d):
The acceleration a and the velocity v of the particle is related as
(e):
The particle attains maximum x at, let's say, , when the following two conditions are fulfilled:
Applying both these conditions,
For ,
Since, c is a positive constant therefore, for ,
Thus, particle does not reach its maximum value at
For ,
Here,
Thus, the particle reach its maximum x value at time
