Here is the answer..
Hope it helps...
Answer:
total momentum before Collison = 10kg·m/s
velocity of combined object = 1.6m/s
Explanation:
For Object(Before Collison)
mass = 1kg
velocity = 10m/s
momentum = 10kg·m/s
For Wooden Block(After Collison)
mass = 5kg + 1kg (as object sticks to it after collison)
=> 6kg
v = ?
momentum = 6v
according to law of conservation of momentum both momentum should be equal
so .
10 = 6v
10/6 = v
v = 1.6m/s
