Answer to Question #60862 in Mechanics | Relativity for Casey

Question

A frictionless pulley system is released from rest and moves 18.3 cm in 1.80351 s. The acceleration of gravity is 9.8 m/s2 . The image depicts a pulley system with two blocks connected together by wire, Block 1, weighing 3kg, is on a frictionless table, while Block 2, connected to the 3kg block (Block 1), is hanging off the table. The pulley being in the middle of Block 1 and Block 2.

What is the value of the mass of Block 2? Assume all surfaces are frictionless. Answer in units of kg.
