M1v1=m2v2 farmula use hoga!
Data:
m1=100gm=100/1000=0.10kg
m2=10kg
u1=0 m/s
u2=0 m/s
v1=1000 m/s
v2= ??
SOLUTION:
m1u1+m2u2=m1v1+m2v2
1*0+10*0=0.1*1000+10v2
0+0=100+10v2
-100=10v2
-100/10=v2
v2=-10m/s.
Answer
m1=100gm=100/1000=0.10kg
m2=10kg
u1=0 m/s
u2=0 m/s
v1=1000 m/s
v2= ??
SOLUTION:
m1u1+m2u2=m1v1+m2v2
1*0+10*0=0.1*1000+10v2
0+0=100+10v2
-100=10v2
-100/10=v2
v2=-10m/s.
