A cop is traveling at a velocity of 24.17 m/s when he is passed by a speeding car traveling at a velocity of 40.29 m/s and accelerating uniformly at 1.77 m/s^2 At the moment the speeding car passes him, the cop accelerates uniformly at 3.31 m/s^2. How long does the cop take to catch up to the speeding car?
1. 11.368 s
2. 23.761 s
3. 20.935 s
4. 26.127

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.

i think its c if i'm wrong
