Question

A bullet of mass 50 gram moving horizontally with velocity 100m second hits and get embedded in a wooden block of mass 450 gram placed on a vertical wall of height 19.6 metre . If the bullet gets embedded in the block then find how far from the wall does the block falls on the ground take g=m/s

Answer 1

here light object is striking the heavy object and the heavy obke t is at rest.soo
m1<<m2 ,v2=0
v1=0-(m2/0+m2)u1+0
v1=-m2/m2u1=-u1
v2=0+0=0 answer

Answer 2

Answer:

here light object is striking the heavy object and the heavy obke t is at rest.soo

m1<<m2 ,v2=0

v1=0-(m2/0+m2)u1+0

v1=-m2/m2u1=-u1

v2=0+0=0 answer
