Answer:
Explanation:
You need to convert furlongs to yards to mm:
Now, we convert fortnight to seconds:
*
The approximate height of the tsunami in Alaska in 1958 is 1720ft
There are several approaches. The most favourable one (in my opinion) is this one:
1. Asking a question
2. Doing a research (how to answer this question)
3. Creating a hypothesis (NOT a thesis!)
4. Experimenting (to prove the hypothesis)
5. Analysing results from the experiment
6. Writing a thesis
<span>In order to determine the speed of the entire assembly, we employ conservation of momentum. Momentum p = mv where m is the object's mass and v is the velocity.
The putty ball's initial momentum p1 = 0.3kg*6m/s = 1.8 kg*m/s
That momentum is conserved, so the momentum of the new system having mass 0.3 kg + 1.2 kg = 1.5 kg is:
1.8 kg*m/s = 1.5kg*v. Solving for v, we find that the velocity is 1.2 meters/second.</span>
