Sagot :
For a disk with radius of 0. 5 m is free to rotate around its center without friction, its angular speed after 1 s is mathematically given as
w=1/(0.5M π^2)
What is its angular speed after 1 s?
Generally, the equation for the Moment of inertia is mathematically given as
I=0.5mx^2
Where
radius = 0. 5 m
Mass=M
Force on edge=F=2N
Time =t
Hence, Torque
T=0.5*2=1.0Nm
Where
T=Ia
w=W0+at
Hence
W=1/I
In conclusion, angular speed after 1 s
I=0.5M π^2
w=1/(0.5M π^2)
