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?

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...
