**GeorgeK**, Thursday, October 4, 2012 at 4:27pm1) Momentum = (150lb+30lb)(20mi/hr) = _______lb*hrs

2) Find half of the above answer

3) momentum = mass x velocity, or

p = mv

Substitute the value of p from step 2 and 30lbs for the mass of the dog in the above equation. Solve for V.

Please note: The unit of momentum here is 1 lb*hr. Not the standard momentum unit but it is conveneient here.
