A block of mass 2kg is moving along the x-axis under the influence of a force whose x-component varies as shown in the graph. The particle is at rest when it is at the origin. Determine the work done by the force as the block moves… a) …from x=0 to x= 4m b) …from x=0 to x=8m Find the speed of the block … c) …at x= 4m. d) …at x= 8m.

pe = weightxheight = 2000x1000=2,000,000joules

not moving. pos accel,

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'm on my way to history not a mistory.
