Questions
The kinetic energy of a body is increased by 300%. The momentum of the body would increase by:
a
50%
b
100%
c
150%
d
300%
detailed solution
Correct option is B
KE = P22m or P2 ∝ KE ----(i)KE2= KE1+ (300100)KE1 = 4KE1From (i) P2P1 = KE2KE1 = 4KE11KE1 = 2It means momentum becomes twice, hence increase in momentum is 100%Talk to our academic expert!
