76 A ball of mass of 0.50 kg moves along a straight line and is acted upon by a net force of F = (–6.00 N) + (1.5 N/m) x . When the ball is located at x = 2.00 m you notice that it has a speed of v = 4.00 m/s. (a) Sketch the force as a function of the position, paying attention to values at the axes. (b) What is the ball's kinetic energy at x = 2.00 m? (c) What is the net work done as the ball moves from 2.00 m to 5.00 m? How can this be indicated on your sketch? (d) What is the ball's kinetic energy when it reaches

Unformatted text preview: x = 5.00 m? (e) What is the speed of the ball when it reaches x = 5.00 m? Force, F Position, x 77 Work from Graphs Graphs of a spring force as a function of its stretch (with 0 being the relaxed or unstretched length) are shown below for two different springs. For each graph, determine the work done by the spring as it changes length from 1 to 4 m. Shade in the part of the graph that represents the work you calculate....
