Please answer ASAP. A 25.0 kg dog decides to go for a solo hike to the top of a 850.0 m tall mountain. 1. How much work does the dog do? 2. If the dog walks along the trail and covers a distance of 2550 m, what is the average force exerted by the dog? 3. Imagine there is a second dog with the same mass that decides to walk the trail but takes an alternative route that zigzags back and forth (its a much easier walk). Which dog does more work?

car stops. he keeps going = he has inertia

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

hypothesising or postulating

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
