The skier leaves from point A from rest and slides on the frictionless track AB, then he continues his motion on the track BCD; under the action of a frictionless force of constant magnitude = ; to stop at D. Consider the skier to be a point object during its motion. Given: g = 10 m/s2 .

the average speed is 24.57 km/hr

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.
