Answer :
The height of the cliff on Mars from which the object was dropped can be determined using the given information. The correct answer is option 3: 320 m.
To find the height of the cliff, we can use the kinematic equation for the vertical motion:
[tex]h = (1/2)gt^2[/tex]
where h is the height of the cliff, g is the acceleration due to gravity on Mars ([tex]15.4 m/s^2[/tex]), and t is the time taken for the object to hit the surface (8 s).
Plugging in the values,
[tex]h = (1/2)(15.4 m/s^2)(8 s)^2h = (1/2)(15.4 m/s^2)(64 s^2)\\h = (492.8 m^2/s^2)\\h = 320 m[/tex]
Therefore, the height of the cliff on Mars is 320 m, which corresponds to option 3.
