Answer:
K.E=365.2 J
Explanation:
Given data
Weight w =953 N
radius r=1.68 m
F=73.9 N
t=2.55 s
g=9.8 m/s²
To find
Kinetic Energy K.E
Solution
From the moment of inertia
The angular acceleration is given as
The angular velocity is given as
So the Kinetic Energy is given as
Answer:
The separation of the 2 points should be 50.0 meters.
Explanation:
According to Rayleigh's scattering criteria the angular separation between 2 points to be resolved equals
Applying the given values we get
thus the linear separation equals
Applying the given values we get
