Answer:
Acceleration due to gravity on that planet, a = 9 m/s²
Explanation:
Initial velocity, u = 0 m/s
Acceleration due to gravity , a = ?
Displacement, s = 72 m
Time , t = 4 s
We have equation of motion s= ut + 0.5 at²
Substituting
s= ut + 0.5 at²
72 = 0 x 4 + 0.5 x a x 4²
a = 9 m/s²
Acceleration due to gravity on that planet, a = 9 m/s²
