Block A has a mass of 20 kg and rests on a frictionless table. A cord attached to block A extends horizontally to a pulley at the edge of the table, block B has a 10 kg mass and hangs over the edge attached to the string.

How would I calculate the tension in the cord?

Answer #1

Give that table is frictionless ,so no frictional forces

Consider Block A

Net Force =Mass*acceleration

-------------(1)

============

Consider block B

Net Force =Mass*acceleration

Put (1) in above equation
