Answer:
Explanation:
Given
Two baseballs are fired into a pile of hay such that one has twice the speed of the other.
suppose u is the velocity of first baseball
so velocity of second ball is 2u
suppose and are the penetration by first and second ball
using
where v=final velocity
u=initial velocity
a=acceleration
d=displacement
here v=0 because ball finally stops
for second ball
divide 1 and 2 we get
as deceleration provided by pile will be same
thus faster ball penetrates 4 times of first ball
