Answer:
Coefficient of friction = 0.836
Explanation:
If v be the speed after one quarter of the circular path
v² = 2as = 2 x 1.85 x 2πr/4 ; v²/r = 1.85 x 3.14 = 5.8
tangential acceleration = 5.8 m/s²
radial acceleration = v² /r = 5.8
total acceleration = √2 x 5.8
m x√2 x 5.8 = m x g xμ
μ = √2 x 5.8 / 9.8 = 0.836
Answer:
Speed of sound inside metal is ≅ 8200 
Explanation:
Given :
Length of metal bar 
m
From general velocity equation,
Where 
speed of sound in air = 343
For finding time from above equation,
sec
Since pulses are separated by 
sec
So we take time difference,
So speed of sound in metal is,
