Bob releases a toy car at the top of the derby car ramp. predict the motion of the car at 6 seconds.

a) the race car decelerates as it approachs in the bottom of the ramp.

b) the car continues at a constant rate in a linear path down the ramp.

c) the derby race circuit will end before 6 seconds so the car will stop.

d) the derby car continues to accelerate as it travels in a straight line.

i think the answer is a, hope this is right, that would be my best guess.

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.
