[0/1 Points] DETAILS PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER The acceleration due to gravity at the surface of a planet depends on the planet's mass and size; therefore other planets will have accelerations due to gravity different from 9.8 m/s2. Imagine an astronaut stands on an alien planet, which has no atmosphere, and throws a rock with a speed of 7.15 m/s in the horizontal direction, releasing it at a height of 1.40 m above the surface of the planet. The rock hits the surface a horizontal distance of 8.50 m from the astronaut. Find the magnitude of the acceleration due to gravity, in m/s2, on this alien planet. 7.11 X What is the direction of the acceleration? How much time does it take the rock to travel the horizontal distance? Knowing this, what constant acceleration relation will allow you to find the acceleration? m/s2 Submit Answer Home My Assignments + Request Extension
