Answer:

If the initial velocity being is a straight line, and the final velocity being 0 km/hr, or o m/s, then:

v(final) = v(initial) + at

0 = 72 Km/h + (-=a * 10 s)

- a * 10 s = 72 km/hr * hr/3600s * 1000m/km = 20m/s

a = - (20 m/s) / (10 s)

a = - 2 m/s^2

That’s 2 m/s^2.

Please give thanks to all my answers and please mark as brilliant and please follow me

Step-by-step explanation:

Formula : distance=speed×time

time.= 10s = 10÷60÷60= 1/360h

speed = 72km/h

distance = 72×1/360 = 0.2km
