We are given
damped harmonic oscillation force = k
mass = m
damping constant = b1
amplitude = a1
driving angular frequency = k/m
I think we asked for the amplitude of the force at different damping constant
The formula to use is
A = (F/ (√(k - m w²)² + (b² w²))
Simply substitute and solve for A in terms of a1
Answer:
a=7.384 m/s^2
Explanation:
let T be the tension in the string, m= mass
and a= acceleration
from the FBD in the attachment we can write
Tcos37°= mg
Tsin37° =ma
dividing both the equations we get
tan37° =a/g
therefore a=g×tan37°
a= 9.81×0.7535 = 7.384 m/s^2
the magnitude of the acceleration a of the train = 7.384 m/s^2
