Question

if two bodies A and B of masses 'm' and '2m' are moving with velocities '2v' and 'v' respectively then
(1) A requires more force to stop in a given time
(2)B requires more force to stop in a given time
(3)both require same force to stop in a given time
(4)same force will accelerate them equally


tick any one

Answer 1

answer is (3) both require same force to stop in a given time

Answer 2

Force is the change in momentum

this momentum for both body is same

i.e. 2mv

therefore the answer is:

(3)both require same force to stop in a given time
