Cam design, s,v,a,j diagram

Design a three-dwell cam to move a follower from 0 to 2.5" in 40deg, dwell for 100deg, fall 1.5" in 90deg, dwell for 20deg, fall 1" in 30deg, and dwell for the remainder. The total cycle must take 10sec. Plot the s,v,a,j diagrams. The polynomial method is to be used to solve the equation. For the graphs, Mathcad or similar program is necessary to graph the solution. I do not know how to solve for the constants necessary to plot the graphs. Also, I do not know how to plot the graphs once I've found all of the necessary information. Thank you for any assistance that can be given.

10-kg mass slides up a 30-deg ramp and then back down

I need a detailed description of each step so I can make sense of what is happening in the problem. This is one of two problems on my last quiz and I failed the quiz (Multiple Choice- Timed online quiz) making a 37.5 F. I only received a 37.5 due to guessing.
