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)

answer: (431,2)
