Question

Two masses,1m 1 and 2m 2, are connected by a light string passing over a pulley. The system is initially at rest. What happens to the acceleration of the system if the mass of 1m 1 is doubled while the mass of 2m 2remains unchanged?

A) The acceleration of the system decreases
B) The acceleration of the system increases
C) The acceleration of the system remains the same
D) The acceleration cannot be determined without additional information

Answer 1

The acceleration of the system will remain the same if the mass of 1m 1 is doubled while the mass of 2m 2 remains unchanged.

Step-by-step explanation:

The acceleration of the system will remain the same if the mass of 1m1 is doubled while the mass of 2m2 remains unchanged. This is because the acceleration of a system is dependent on the net external force acting on the system and the mass of the system. According to Newton's second law of motion, the acceleration of a system is inversely proportional to its mass.
