Modify the mathematical ball-and-tower-model expression, h(t) = -16 t2+ v t + s, assuming a perfectly elastic collision, so that it works for all time t > 0. Implement in Excel or Python. Execute and plot your new expression in 1-second intervals from t = 0 to t = 300 sec. Use v = 100 and s = 1000 and Execute and plot again using v = 0 and s = 2000.
