An object of mass 1.1 \(kg\) travelling in a straight line with a velocity of 6 ms1 collides with, and sticks to, a stationary wooden block of mass 6 \(kg\). Then they both move off together in the same straight line. Calculate the total momentum just before the impact and just after the impact. Also, calculate the velocity of the combined object. 
 
1. Total momentum just before the impact \(=\)  \(kg\)ms1
 
2. Total momentum just after the impact \(=\)  \(kg\)ms1
 
3. Velocity of the combined object \(=\)  ms1
