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?(adsbygoogle = window.adsbygoogle || []).push({});

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?
