Answer 1

@Outkast3r09 @Edutopia

Answer 2

well torque is easy

Answer 3

\[it's the we know the lever arm however we need to make the force perpendicular to the arm i think if i remember right

Answer 4

we need to find the perp force of that force on it which is a component of that force

Answer 5

so if you look t's the sin of that angle

Answer 6

so now you have
\[\tau=fRsin(\theta)=2*3*sin(30)\]

Answer 7

you're given velocity so you can find angular velocity

Answer 8

now you need to find the moment of inertia for hte object... you can perhaps find this using torque equation

Answer 9

\[\tau=fR=I\alpha\]

Answer 10

@Outkast3r09 i go the torque i need the (a) part

Answer 11

angular momentum

Answer 12

you need to find hte moment of inertia of this object somehow

Answer 13

I can also use r x mv right
