Answer:
h=20.38 m
Explanation:
Given that
Initial speed of object u = 20 m/s
Acceleration 
We know that
Here acceleration and velocity is in opposite direction so the object will come rest after reaching at distance h.When body will reach at its highest position then velocity will become zero(v=0).
Now by putting the values
h=20.38 m
It is b i had that qustion
Answer:
.487 s⁻¹
Explanation:
Let damping constant be τ . The equation of decreasing amplitude can be written as
A = A₀ 
A / A₀ =
At t = 9.43 s , A / A₀ = .01
.01 = 
ln.01 = - 9.43 τ
-4.6 = -9.43τ
τ = .487 s⁻¹
