Acceleration of 2 Rubber Bands on an Object

[gbedenba]

Homework Statement

Two rubber bands pulling on an object cause it to accelerate at 1.6 m/s2

(a) What will be the object's acceleration if it is pulled by six rubber bands? Answer: 4.8 m/s/s (correct)
(b) What will be the acceleration of seven of these objects glued together if they are pulled by two rubber bands?

Homework Equations

The Attempt at a Solution

got 4.8 m/s/s for A...that is right...don't know how to get b

Two rubber bands, one object, a = 1.6 m/s².

Two rubber bands, seven objects, a = ?

When the mass is seven times as big and the force is the same, the acceleration will be ...? Think Newton's Second Law.

I would say that the acceleration of the object will depend on various factors such as the strength and elasticity of the rubber bands, the mass and shape of the object, and the surface it is being pulled on. Without this information, it is difficult to accurately predict the acceleration of the object. Additionally, the arrangement and orientation of the rubber bands may also affect the acceleration of the object. Therefore, further experimentation and analysis would be needed to determine the exact acceleration in this scenario.
