Mount Olympus is the largest known mountain in the Solar System. It is located in the western hemisphere of the planet Mars. An astronaut launches a measuring instrument from the top of this mountain upwards with an initial velocity of 25 m / s. Upon his return, the astronaut cannot catch the instrument so it begins to descend towards the Martian surface.
Determine
a. The time required for the instrument to reach its maximum heightb. Maximum heightc. The time required for the instrument to return to the height from which it was launched and its speed at that instant.d. The time required for the stone to reach the surface of Mars.and. Repeat all the previous items assuming Mount Olympus was on Earth.
