5. Two masses mi = 5 kg and m2 = 4 kgtied to a string are hanging overlight frictionless pulley. What is theacceleration of each mass when left freeto move? (g = 10ms-2)

Answer»

Net force acting on the system will be 5g -4g = (5-4)*10 = 10N

now total mass of system = (5+4) + 9kg

so, acceleration = F/m = 10/9 m/s².

thank you!
