Question

The figure shows an acceleration-versus-force graph for three objects pulled by rubber bands. The mass of object 2 is 0.18kg
(I'll post the figure in the comments)
1)What is the mass of object 1?
2) What is the mass of object 3?
Explain.

Answer 1

do you know relation between force, mass and acceleration?

Answer 2

f=ma

Answer 3

good, do you know what is slope?

Answer 4

for each of them x axis over y axis is mass

Answer 5

for 2, 5F/5a_1=0.18kg, using this you can find mass of others

Answer 6

No, I dont know what the slope means. Are you saying slope=mass?

Answer 7

actually here inverse of slope corresponds to mass.

Answer 8

from 2 you get F/a1=0.18kg
for 1 you have 2F/5a1=2*0.18/5=0.072kg

Answer 9

For onject 2
F=ma
5=m*5a1
5=0.18*5a1
a1=?

Answer 10

For object 1
F=ma
2=m*5a1
m=?

Answer 11

For object 3
F=ma
5=m*2a1
m=?
