    Rigid Body Dynamics: balls colliding

    okay, thank you. Do you have any relevant calculations in mind? I find it a little tough.

    Rigid Body Dynamics: balls colliding

    Homework Statement I want to analyse two colliding balls, rolling flat on a billiard table. I have recorded two collisions from above the table. A 1D collision and a 2D collision. In both collisions only 1 of the balls are rolling before the collision. Known is: mass of the balls: m1=207g...

    Calculating the Moment of Inertia of the Sun for Determining Rotational Energy

    I want to find the rotational energy of the sun. Erot=1/2*I*ω2 m=1.9891*10^30 kg r=6.955*10^5 km When I am using the formula for a sphere's moment of inertia: I=2/5*m*r2 I'm getting 3.848671797*1047 km*m2 Can i find the moment of inertia in another way? the moment of inertia needs...
