Name: ppose the equation for an object that falls from location is h = -= gtz + ho , where he is the initial height of the Gravity object and the acceleration of gravity on planet ivi 8.2 m/s and on planet Brianna the acceleration of gravity is 4.23. If an object is dropped from a initial height of 400 m. (Round your answer to the nearest tenth) a. Calculate the time it takes to reach the ground for each planet. b. On which planet did the object reach the ground first? Explain your answer. c. If an object was dropped from a hot air balloon 2500 m off the ground on planet Ivi. How long will it take the object to hit the ground? (Round your answer to the nearest tenth of a second. Explain how you arrived at your answer.)
