Astudent developed an experiment to measure the acceleration of the gravity. in the experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. the distance between the two photogates was 53.0 cm and the recorded time was 325 ms (millisecond). calculate the magnitude of the velocity at the lower photogate.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
