Question

If the acceleration due to gravity is 10ms and the unit of length and time are changed in kilometers and hour respectively the numerical value of acceleration is

Answer 1

your answer is as per me 36 kmhr

Answer 2

1 km = 1000 m ==> 1 m = 10^-3 km
1 h = 3600 s ==> 1 s = 1/3600 h

10 m/s^2
= 10 × (10^-3 km) / (1/3600 h)^2
= 129600 km/h^2

Numerical value of acceleration is 129600 km/h^2

[Note: Unit of acceleration is m/s^2]
