Explanation:
Given that
Mass of the ladder ,m= 6 kg
L= 2 m
Mass of artist ,M= 42 kg
The total moment of inertia of the both ladder and artist ,I
Here
I=50 kg.m²
The angular frequency f given as
Here 
D=1 m
f= 0.48 s⁻¹
Answer:
Speed is 0.08 m/s.
Explanation:
Given the distance that the bird flies = 3.7 meters
The time is taken by the bird to fly the 3.7 meters = 46 seconds
We have given distance and time. Now we have to find the speed at which the bird flies. So, to calculate the speed of the bird we have to divide the distance by the time.
Below is the formula to find the speed.
Speed = Distance / Time
Now insert the given value in the formula.
Speed = 3.7 / 46 = 0.08 m/s
