Answer:
Part a)
Part b)
Explanation:
Part a)
as the mass of the suspension system is given as
also we have
so now for force balance we have
Part b)
Now we know that amplitude decreases by 63% in each cycle
so after one cycle the amplitude will become 37% of initial amplitude
so it is given as
also we know
here t = time period of one oscillation
so it is
now damping constant is
Physical forces because physical force can only move the box
Answer:
its obviously D if all the other says "incorrect answer" XD
