Vector has a magnitude of 130 units and points 31.0 ° north of west. vector points 66.0 ° east of north. vector points 14.0 ° west of south. these three vectors add to give a resultant vector that is zero. using components, find the magnitudes of (a) vector and (b) vector .

thermal energy is the answer

i don't understand. explain it clearly

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

the inner core.

good luck: )
