Answer:
The amplitude after 75 s, x(t) = 0.558 m
Given:
Initial Amplitude, A = 1.8 m
time constant, = 32 s
Solution:
Now, to calculate the amplitude of the damped oscillation after 75 s, we use the relation:
Amplitude after 75 s, x(t) = A
Now, putting the value in the above relation:
x(t) = 1.8
x(t) = 1.8
x(t) = 0.558 m
As we know that the velocity at any instant is defined as slope of displacement time graph at that instant
so we will have
now we will say
slope of the graph is also defined as
now on increasing the value of the slope we will have more steep graph
so more steep graph will have more value of theta
so for steep graph
so value of the velocity will be large at steep graph
