A stone is dropped from a height 
. It hits the ground with a certain momentum 
. If the same stone is dropped from a height 100% more than the previous height, the momentum when it hits the ground will change by
Text Solution
Verified by ExpertsThe correct answer is:
B
: When a stone is dropped from a height h,it hits the ground with a momentum 
where m is the mass of the stone.
When the same stone is dropped from a height 2h(i.e. 100% of initial), then its momentum with which it hits the ground becomes
(Using (i)) 
(ii)
% change in momentum
