Given data:
* The distance traveled by the object is 64 m.
* The time taken by the object to travel the distance is 4 seconds.
* The initial velocity of the object is 0 m/s.
Solution:
By the kinematics equation, the acceleration due to gravity on Planet X is,
where S is the distance traveled, u is the initial velocity, t is time taken, a is the acceleration due to gravity on Plant X,
Substituting the known values,
