Ohhhh right. Wow, quite a fail on my behalf. So now I calculated Torque as F*d ((3*0.75)*0.3) and got 0.675. Then I divided this by 10 (calculated angular acceleration - 3/0.3) and got 0.068. This is an option...but is it correct? Or should I factor in gravity to my force calculation?

Homework Statement So basically there is a wheel with a radius of 0.3 m. A light cord wrapped around the wheel supports a 0.75-kg object that accelerates at 3 m/s^-2 downwards. What is the moment of inertia of the wheel? (no friction) Homework Equations I=mr^2 T=I(alpha) (alpha)=ra...

Homework Statement A 5.0-kg object has a velocity of 6.0 m/s, east when it explodes into two 2.5-kg objects. After the explosion one of the objects has a velocity of 4.0 m/s at an angle of 50° north of east. What is the magnitude and direction of the velocity of the other object after...
