Describe why using the simulation is a good method for studying projectiles. Clearly identify the error sources the simulation e

liminates or minimizes. Also, run tests to determine how well the simulation represents projectile motion and identify limitations.

What is the most likely reason it is dangerous to break open a compressed gas tank?

erastova [34]

The main reason why it's very dangerous to open compress gas tank is it can cause major disaster not only in human but also in plants and animals. Compress gas is flammable. And it's like a bomb the damage of gas tank is very catastrophic. It is very harmful if mishandled.

Which of the following would have more momentum than fiona, a 313kg hippo, running at 8m/s?

kap26 [50]

Let's calculate the momentum of Fiona, given by the product between its mass and its speed:
$p=mv=(313 kg)(8 m/s)=2504 kg m/s$

Now let's compare it with the momentum of the other animals:
a) the mass of the sea turtle is missing, so we cannot calculate its momentum.
b) the momentum of the dolphin is
$p=mv=(150 kg)(18 m/s)=2700 kg m/s$
c) the momentum of the horse is
$p=mv=(380 kg)(4 m/s)=1520 kg m/s$
d) the momentum of the lion is
$p=mv=(190 kg)(11 m/s)=2090 m/s$

And we can see that the correct answer is b), because the momentum of the dolphin is greater than the momentum of Fiona.
