The acceleration due to gravity on the surface of a planet depends on the mass and size of the planet; therefore, other planets will have accelerations due to gravity other than 9.8 m / s2. Imagine an astronaut standing on an alien planet, which has no atmosphere, and throws a stone with a velocity of 7.35 m / s in a horizontal direction, dropping it at a height of 1.40 m above the surface of the planet. The rock hits the surface at a horizontal distance of 9.50 m from the astronaut. Find the magnitude of the acceleration due to gravity, in m / s2, on this alien planet.
