Acar moves with constant acceieration of -0.s m/s? on a straight portion of the road. att- 0s the car has a velocity of 69 mph, how far does the car travels until its speed is reduced to haif? select one: a. 1.12 km o b.0.71 km c. 3.57 km d. 1.02 km

b) d = 0.71 Km

Explanation:

Car kinematics

Car 1 moves with uniformly accelerated movement

Formula (1)

d: displacement in meters (m)

v₀: initial speed in m/s

vf: final speed in m/s

a: acceleration in m/s²

Equivalences:

1mile = 1609.34 meters

1 hour = 3600s

1km = 1000m

Known data

a = -0.5 m/s²

Distance calculation

We replace data in the Formula (1)

okay i have so many questions. but the big one here is: um wt..f is this mess? ?

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
