PROBLEM 3: In a Jupyter notebook, define a functions that connect (0,0) to (1, -1), such that the second derivative is zero just at one point. Plot the function using matplotlib, and mark on the plot where the second deerivative is zero. Compute the time it takes for a particle to reach the end point. Use the class I used in the lecture.
