26. Snoopy, in hot pursuit of the Red Baron, is flying his vintage warplane in a “loop-the-loop" path. His instruments tell him that the plane is level (at the bottom of the loop) and travelling at a speed of 180 km/h. He is sitting on a set of bathroom scales. He notes that the scales show four times his normal weight. What is the radius of the loop, in metres?

13. A skier/snowboarder starts at rest at the top of a snowy (friction-free) hill with height h₁. After the bottom of this hill there is a small "jump" hill. The top of the jump has height h, and a curvature of radius R. What is the minimum height of the starting hill, himin, so that the skier/snowboarder jumps or "catches air" at the top of hill 2? Solve for himin in terms of h₂, R, and g. Hint: if the skier/snowboarder jumps, he/she/they loose contact with the snowy ground. h₁ to jump!

Homework Problem 31: A professor is swinging a ball (Mass 0.358Kg) in a vertical circle at a constant speed. The length of the string is 0.29m. The professor measures the tension and discovers that it is 1.715 times larger at the bottom of the circle than at the top. What is the speed of the swinging mass? Note: The acceleration due to gravity is directly downwards.
