A 5.0 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with position as shown below. (a) How much work is done by the force as the block moves from the origin to x = 8.0 m? (b) It the block has a speed of 3.1 m/s at the origin, what is its speed when it reaches x = 8.0 m? m/s 10 8. 2 4 Position (m)
