Assuming a 10% trophic efficiency, the herbivore (primary consumer) will get 10% of the producer energy. Then, the second consumer that eat the herbivore will get 10% of the primary consumer energy, so it is 10%*10%= 1% of the primary producers. 
Then, the t<span>ertiary consumer should get 0.1% of the primary producers' energy.</span>

This is a momentum question: 
Momentum is always conserved so the momentum before and after a collision must be equal so:
The velocity of the two objects after they collide and dont stick together if no KE is lost is dependent on the mass of each of the objects by: 

Where i is initial and f is final meaning before and after the collision
