After a model rocket reached its maximum height, it then took 5.0 seconds to return to the launch site. what is the approximate maximum height reached by the rocket? [neglect air resistance.]

The maximum height reached by the rocket is 122.5 m.

The given parameters;

The maximum height of the model rocket is calculated by applying second equation of motion;

h = v₀t + ¹/₂gt²

where;

h = 0  + (0.5 x 9.8 x 5²)

h = 122.5 m

Thus, the maximum height reached by the rocket is 122.5 m.
