A block of mass m1=5.0 kg moves in uniform circular motion with a radius of 3.0m on a frictionless table. The block is connected by a string and a pulley to another block of mass m2 which hangs through a hole in the center of the table, as shown in the figure. If block 1 is moving at a speed of v=2.0 m/s, what is the mass of block 2?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

answer; i believe the correct answer is (40,000 j) good luck
