. A person shoots a rocket up into the air and it travels 60 meters in the northern direction. A crosswind pushes the rocket 30 m to the West. Graphically determine the magnitude and direction of the resultant.

temp rises, and expansion

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

e/c, where e is its total energy
