a and b are two bodies with masses 10kg and 50 kg respectively.which has more inertia
Answers
Answer:
A= 10kg
B=50kg
A×B
10×50=500kg
Answer:
pls mark it as brainliest
Explanation:
We know that inertia increases with mass as well as decreases with decrease in the same. We see here: Body B has more mass than Body A hence has more inertia.
Horizontal force,F=600 N
Mass of body A, m
1
=10 kg
Mass of body B, m2=20 kg
Total mass of the system, m=m1+m2=30 kg
Using Newtons second law of motion, the acceleration (a) produced in the system can be calculated as:
F=ma
a=
m
F
=
30
600
=20m/s

When force F is applied on body A:
The equation of motion can be written as: F−T=m
1
a
T=F−(m
1
)a
=600−10×20=400 N (i)
When force F is applied on body B:
The equation of motion can be written as:
F−T=m
2
a
T=F−(m
2
)a
T=600−20×20=200 N (ii)
which is different from value of T in case (i). Hence our answer depends on which mass end, the force is applied.
