Short Answer

FIGURE shows an acceleration-versus-force graph for three

objects pulled by rubber bands. The mass of object 2 is 0.20 kg.

What are the masses of objects 1 and 3? Explain your reasoning

mass of the object 1 is 0.08 kg and mass of the object 3 is 0.5 kg

See the step by step solution

Step by Step Solution

Step 1.Given information

in question the acceleration-versus-force graphs is given and this graph give the information about the rubber bands who pulled the three objects. also give the mass of the second rubber band and it is 0.2 kg so from that find the masses of the other two rubber bands 1 and 3.

Step 2

Here, use the Newton second law who say that rate of change of momentum is directly proportional to force.

Step 3

using the Newton second law and we find the value of a1

Here, mass of second object given which 0.20 kg and from graph find the force and acceleration so the values of them are 4 and 4a1

Step 4

Now again use the Newton second law to find the mass of object 1 and put the value of a1 which is already define in step 1

from the graph take the value of force and acceleration which are 2 N and 5a1

Step 5 

Now again use the Newton second law to find the mass of object 3 and put the value of a1 which is already define in step 1

from the graph take the value of force and acceleration which are 5 N and 2a1

Therefor the mass of the object 1 is 0.08 kg and mass of the object 3 is 0.5 kg
