PLEASE HELP! I GIVE LOTS OF POINTS!

Two blocks, with masses m and 3m , are attached to the ends of a string with negligible mass that passes over a pulley, as shown above. The pulley has negligible mass and friction and is attached to the ceiling by a bracket. The blocks are simultaneously released from rest.

(a) Derive an equation for the speed v of the block of mass 3m after it falls a distance d in terms of m , d , and physical constants, as appropriate.

(b) Determine the work done by the string on the two-block system as each block moves a distance d .

(c) The acceleration of the center of mass of the blocks-string-pulley system has magnitude aCOM. Briefly explain, in terms of any external forces acting on the system, why aCOM is less than g.

Answer:

this hurts my brain. bro i'm going into physics next year and im over here think physics is easy well you just proved me wrong

Explanation:

ItsDodo
first of all you gotta find the acceleration from the equations of motion, but i have one question, how come mass (m) is heavier than mass (3m) ?
