Q7. The 5-kg ball is connected to a spring with spring constant k = 220 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= 380 N (in the direction shown in the image) acting on the ball, the spring is stretched to a new length 1.3 m. If the ball starts from rest, determine its speed at the end of this process. Neglect the mass of the spring, and the slope is smooth. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s². F |15° 40°

Transcribed Image Text:Q7. The 5-kg ball is connected to a spring with spring constant k = 220 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= 380N (in the direction shown in the
image) acting on the ball, the spring is stretched to a new length 1.3 m. If the ball|
starts from rest, determine its speed at the end of this process. Neglect the mass of
the spring, and the slope is smooth. Please pay attention: the numbers may change
since they are randomized. Your answer must include 2 places after the decimal
point, and proper Sl unit. Take g = 9.81 m/s².
