Question

two stones having masses in the ratio 3 is to 2 at dropped from the Heights in the ratio 4 is to 9 the ratio of magnitudes of the linear momentum just before reaching the ground is( neglect air resistance)

Answer 1

Heya

As velocity just after drop is root2gh for every object

Therefore


Ratio of masses = M/m = 3:2
Ratio of height= H/h = 4:9
u = 0m/s v = ?
g=10m/s
For finding the velocity of the stones with H;

velocity with h height;

Ratio of linear momentum of the 2 stones;
P/p = MV/mv=1:1
Therefore, the ratio of the linear momentum of the two stones is 1:1
