Then under the applied force F, the spring is stretched to 0.6 m. Determine the total work done to the ball during this process. The slope is smooth. k = 300 N/m (a) 151 J F = 400 N (b) 254 J 15 40 (c) 99.1 J (d) 306 J Riswanti SigaliNGGING, STP, M.Si, Ph.D ENGINEERING MECHANICS DYNAMICS CODE :TEP 2 207 P
