Momentum and CollisionHard
Question
A stone is dropped from a height h. It hits the ground with a certain momentum P. If the same stoneis dropped from a height 100% more than the previous height, the momentum when it hits the groundwill change by
Options
A.100%
B.68%
C.41%
D.200%
Solution
Momentum 
P′ = P√2
⇒ Change in momentum is 41%
P′ = P√2⇒ Change in momentum is 41%
