Ω = 2.81
A = 0.232
k = 29.8
x = A cos(ωt + Ф)
at t = 0:
x = A = A cos(ωt + Ф) = A cos(Ф)
Ф = 0
at t = 1.42, with Ф = 0:
x = A cos(ωt)
U = 1/2 k x² = 1/2 k [A cos(ωt)]²
Answer:
The __law__ conservation
of state that either energy may produced nor destroyed
Answer:
The new time period is
Explanation:
From the question we are told that
The period of oscillation is
The new length is
Let assume the original length was
Generally the time period is mathematically represented as
Now I is the moment of inertia of the stick which is mathematically represented as
So
Looking at the above equation we see that
=>
=>
=>
Answer:
44.1613858478 m/s
Explanation:
t = Time taken
u = Initial velocity = 0
v = Final velocity
s = Displacement = 99.4
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
If air resistance was absent Dan Koko would strike the airbag at 44.1613858478 m/s
