While ice skating, you unintentionally crash into a person. your mass is 60kg
and you are traveling east at 8.0m/s
with respect to the ice. the mass of the other person is 80kg
and he is traveling north at 9.0m/s
with respect to the ice. you hang on to each other after the collision. in what direction and at what speed are you traveling just after the collision?

The speed is 6.1m/s with an angle of 56.3 degrees north of east.

Explanation:

We meed to apply the Linear momentum theorem:

The magnitude of the velocity is given by:

and the angle:

prolly a beacuse the momentuem the car has increases while going down hill

in most common fires, oxygen is needed for an oxidation reaction to takes place. the combination of oxygen with any element as fuel can create fire and combustion will occur especially if wood, light materials and other combustible things are combine with oxygen.
