A small, solid sphere of mass 0.2 kg and radius 40 cm rolls without slipping along the track consisting of slope and loop-the-loop with radius 1.5 m at the end of the slope. It starts from rest near the top of the track at a height h, where h is large compared to 40 cm. What is the minimum value of h (in terms of the radius of the loop R) such that the sphere completes the loop?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
