I didn't exactly ask a question when posting, but i wanted to know if my math makes sence. i hope it does

I plugged in some numbers, the mass of the lever arm was 0.045 kg and its length was 0.18 meters The mass of the rock I am launching was 0.205 kg and its distance from the pivot was 0.15 meters

This is the catapult. At equalibrium the spring is 0.09 meters in length. When its fully stretched out its 0.225 meters long and I place a rock (0.205 kg) close to where my finger is on the catapult. The catapult starts with this much energy because 1/2 * k * x^2 90.54 is the spring constant...

Ok, this makes sense, i appreciate the help. Thanks!

What kind of experiment can I design to determine the actual value of the moment of inertia. What should I instruct the sphero to do and what data should I collect?

Should I account for the rotational energy of the lever arm or will that be very little

I know the spring constant of my spring, 90.54 n/m The spring is stretched 13.5 cm Im launching of a deck that is 1.75 meters high
