3.0 m s-2 =.... km h-2
Here we have to convert m/s2 into km/h2
1 km = 1000 m
1 m = 10-3 km
1 s = 
h
Substituting the above values
3 m s-2 = 3 × 10-3 km × {
h}-2
= 3.88 × 104 km h-2
3.0 m s-2 = 3.88 × 104 km h-2

3.0 m s-2 =.... km h-2
Here we have to convert m/s2 into km/h2
1 km = 1000 m
1 m = 10-3 km
1 s = h
Substituting the above values
3 m s-2 = 3 × 10-3 km × { h}-2
= 3.88 × 104 km h-2
3.0 m s-2 = 3.88 × 104 km h-2
