Q12. A 2.9-kg collar travels down a smooth slope as shown. The spring has unstretched length of 8 m and spring constant k = 34 N/m, and it is always horizontal. If at s1 = 13 m the collar has speed of 11 m/s, determine its speed when it gets to s2 = 7 m. 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 2 places after the decimal point, and proper SI unit. Take g = 9.81 m/s2.
