Two particles(A and B) each of mass 10kg are attached to a massless rod on each on opposite ends of the rod. The rod is placed horizontally on a fulcrum. Particle A is 10 cm away from the fulcrum. And particle B is 70cm away from the fulcrum. The rod is now released.(adsbygoogle = window.adsbygoogle || []).push({});

What is the magnitude of the initial acceleration of particle A?

What is the magnitude of the initial acceleration of particle A?

My solution so far

B_torque - A_torque

= mgb - mga

= mg(0.7)-mg(0.1)

=0.6mg

Torque = Iα

I = m(a^2 + b ^2)

Thats the only thing I can think off right now. Totally stuck have no idea what to do.

Wasn't in class when this lesson was given so i have no idea what i am doing.
