u=32km/hr
v=54km/hr
t=8s

u= 32*1000/3600= 80/9 m/s
v= 54*1000/3600= 15 m/s

acc = change in velocity / time taken
acc= final velocity - initial velocity / time taken
acc= 15-80/9 m/s / 8s
acc= 55/72 m/s

If a car changes its velocity from 32 km/hr to 54 km/hr in 8.0 seconds, what is its acceleration?
