Question

ats are pro
springs.
7. Two bodies A and B of the same mass are moving
with velocities v and 3v respectively. Compare their
a. inertia b. momentum c. the force needed to stop
them in the same time. [Ans. a. 1:1 b. 1:3 c. 1: 3]​

Answer 1

Answer:

(a) Since inertia is a measure of mass which is same for both bodies, so the ratio of inertia for two bodies will be 11

(b) Momentum

P=m×v

P1=m×v=mv

P2=m×3v

P2P1=3mvmv=31

(c) Force

F×T=Momentum

F=TMomentum

F1=11

F2=13

F2F1=31
