Q4. The 9-kg ball is connected to a spring with spring constant k = 100 N/m and unstretched length of 0.8 m. Initially the spring is compressed and has length 0.5 m. Then under the constant applied force F = 340 N (in the direction shown in the image) acting on the ball, the spring is stretched to a new length 1.4 m. Determine the work done by the spring to the ball during this process. Please pay attention: the numbers may change since they are randomized. Negative sign must be included if the work done is negative. Your answer must include 1 place after the decimal point, and proper Sl unit. M F 150 40°
