Q5. The 8-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 1.3 m. Determine the work done by weight to the ball during this process. The slope is smooth. 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. Take g = 9.81 m/s2. F |15° 40°

Transcribed Image Text:Q5. The 8-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 1.3 m. Determine
the work done by weight to the ball during this process. The slope is smooth. 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 SI unit. Take g = 9.81 m/s2.
