← A ball is thrown with the same speed at two different angles, θ and 90° - θ, and lands 40 m away on level ground both times. If H₁ and H₂ are the greatest heights reached in the two throws, then H₁H₂ isTwo light springs, of force constants 200 N/m and 300 N/m, are joined end to end. The free ends are pulled apart, stretching the pair. The ratio of the energy stored in the first spring to that in the second is →
