3. If you start at the equator and travel to 100 N latitude, approximately how many kilometers (or miles) north of the equator will you be? Take the circumference of the Earth to be 40,000 kilometers (24,900 miles). Show your calculations.

travel = 1111.11 km or ( 691.66 miles ) north of the equator

Explanation:

given data

travel = 10° N latitude

circumference of the Earth = 40,000 kilometers

solution

when we start at equator and travel whole world and finally reach that same point

so we cover 40,000 km  and that is circumference of Earth

so that we cover = 360° latitude

and here distance travel in each degree of latitude will be

distance travel in each degree =

distance travel in each degree = 111.11 km

so here for travel to 10 degrees N

so travel is = 111.11 ×  10 =

travel = 1111.11 km or ( 691.66 miles ) north of the equator

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
