19. Submarine Search Project If you have access to a computer ities, draw the spiral search p given values of v, va, and d. One must first compute ti, the time when the spiral search begins, and then draw the spiral starting from t 2 t1. (a) vs = 10 mph, vd = 50 mph, d = 4 miles (b) vs = 10 mph, va = 30 mph, d = 4 miles (c) vs = 10 mph, vd = 15 mph, d = 4 miles (d) v.-10 mph, vd = 12 mph, d = 4 miles
