Suppose the equation for an object that falls from location is h = - gt2 + ho, where he is the initial height of the miject and g is 7.5 m/s" the acceleration due to gravity. Calculate the time it takes to reach the ground from the following initial heights ho. (Round your answer to the nearest tenth) 1. 300 m 2 . 1000 m 3. 50 m 4. 500 m If we change the acceleration to gravity to 5.7 m/s how does that change the time before the object hits the ground for the 4 problems above? Use same formula h = - gt2 + ho (Round answer to the nearest tenth) 2 . 1000 m 1. 300 m 4. 500 m 3 50 m
