An object of mass 20 kg is released at point A, slides to the bottom of the 30° incline, then collides with a horizontal massless spring, compressing it a maximum distance of0.80 m (see below). The spring constant is 525 N/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. (Due to the nature of this problem, do notuse rounded intermediate values in your calculations-including answers submitted in WebAssign.)A2.0 m30°www(a) What is the speed of the object (in m/s) at the bottom of the incline?4.0988m/s(b) What is the work of friction (in J) on the object while it is on the incline?148.402× J(c) The spring recoils and sends the object back toward the incline.
