Atwood\'s machine. Two masses are connected by a light string over a frictionles

Question

Atwood's machine. Two masses are connected by a light string over a frictionless massless pulley. They are released from rest and the acceleration is seen to be 1 m/s*2. If the mass that is accelerating upwards is 2kg, what is the tension in the rope? Atwood's machine. Two masses are connected by a light string over a frictionless massless pulley. They are released from rest and the acceleration is seen to be 1 m/s*2. If the mass that is accelerating upwards is 2kg, what is the tension in the rope?

Explanation / Answer

By applying force equation on the given mass,

T - mg = ma

T = ma + mg

= 2*9.8 + 2*1

= 21.6 N ANSWER
