A wheel of radius 0.2m is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is 0.05kg(m^2). A massless cord wrapped around the wheel is attached to a 2kg block that slides horizontally. If a horizontal force of magnitude P=3N is applied to the block, what is the angular acceleration of the wheel?
r=0.2m
I=0.05kg(m^2)
m=2kg
P=3.0N
[tex]T = rFsin \theta[/tex]
[tex]T = 0.6[/tex]
[tex]T=I \alpha[/tex]
[tex]T = 12RPM^2[/tex] Units?
im guessing this is wrong because I never had to use the mass anywhere
Can anyone help?
