Acar traveling at 23m/s starts to decelerate steadily. it comes to a complete stop in 7 seconds. what is the acceleration?

The car has an initial velocity of 23 m/s and a final velocity of 0 m/s. Recall that for constant acceleration,

The car stops in 7 s, so the acceleration is

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.)

the rearrangement of particles in a physical change. hope this
