Un avió de 10000kg vola horitzontalment a 9 km d'altura i té una energia mecànica de 109 J, calculeu: a) Les energies potencial i cinètica en aquesta posició. b) La seva velocitat.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

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.)
