Starting at time t = 0, net force Fi is applied to an object that is initially at rest. Part A If the force remains constant with magnitude F1 while the object moves a distance d, the final speed of the object is vị. What is the final speed v2 (in terms of v1) if the net force is F2 = 2F, and the object moves the same distance d while the force is being applied? Express your answer in terms of vị. | ΑΣφ ? v2 = Submit Request Answer Part B Complete previous part(s)

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.
