1}800m/s
2}80m/s²
Explanation:
1]first convert the kilometers to meters so as to obtain similar units;
16×1000=16000m (1Km=1000m)
then divide the ditance by time:
speed=distance/time
=16000m/2s
=800m/s
2]acceleration=(initial velocity -final velocity)/time taken
=(800m/s-0m/s)/10s
=800m/s/10s
=80m/s²
