Answer:
exponential
Explanation:
type of function that describes the amplitude of damped oscillatory motion is exponential because as we know that here function is
y = A × × cos(ωt + ∅ ) ..................................... ( 1 )
here function A × is amplitude
as per equation ( 1 )it is exponential
so that we can say that amplitude of damped oscillatory motion is exponential
Answer:
a = 3.125 [m/s^2]
Explanation:
In order to solve this problem, we must use the following equation of kinematics. But first, we have to convert the speed of 90 [km/h] to meters per second.
where:
Vf = final velocity = 25 [m/s]
Vi = initial velocity = 0
a = acceleration [m/s^2]
t = time = 8 [s]
The initial speed is zero as the bus starts to koverse from rest. The positive sign of the equation means that the bus increases its speed.
25 = 0 + a*8
a = 3.125 [m/s^2]
