Astudent on a skateboard is moving at a speed of 1.40 m/s at the start of a 2.25 m high and 12.4 m long incline. the total mass is 48.0 kg, air resistance and rolling resistance can be modeled as a constant friction force of 41.0 n, and the speed at the lower end of the incline is 6.00 m/s. determine the work done (in j) by the student as the skateboard travels down the .

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.
