Q4. The 3-kg ball is connected to a spring with spring constant k = 160 N/m and unstretched length of 0.8 m. Initially the spring is compressed and has length 0.6 m. Then under the constant applied force F= 240 N (in the direction shown in the image) acting on the ball, the spring is stretched to a new length 1.5 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. F |15° 40° Your Answer:

Transcribed Image Text:Q4. The 3-kg ball is connected to a spring with spring constant k = 160 N/m and
unstretched length of 0.8 m. Initially the spring is compressed and has length 0.6 m.
Then under the constant applied force F= 240 N (in the direction shown in the
image) acting on the ball, the spring is stretched to a new length 1.5 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 SI unit.
