Work Energy and Power - Result Question 30

33. Two masses of 1g and 9g are moving with equal kinetic energies. The ratio of the magnitudes of their respective linear momenta is [1993]

(a) 1:9

(b) 9:1

(c) 1:3

(d) 3:1

Show Answer

Answer:

Correct Answer: 33. (c)

Solution:

  1. (c) 12(1)v12=12(9)v22

v12v22=9 or v1v2=3

Ratio of their linear momenta

=m1v1m2v2=19×(3)=13
