Block A has a mass of 4.1 kg, and it is on a frictionless surface. A string tied to this mass passes over a frictionless pulley, and is attached to a hanging block (Block B), as shown in the image below. The blocks then accelerate at 2.3 m/s/s.

Question

Block A has a mass of 4.1 kg, and it is on a frictionless surface. A string tied to this mass passes over a frictionless pulley, and is attached to a hanging block (Block B), as shown in the image below. The blocks then accelerate at 2.3 m/s/s.
What is the mass of Block B?

drwls · Answer

a = g*Mb/(Mb + Ma) See if you can derive that equation Solve for Mb
