Problem 10: An elementary student of mass m = 22 kg is swinging on a swing. The length from the top of the swing set to the seat is L = 3.3 m. The child is attempting to swing all the way around in a full circle.
A small block with mass m = 17 kg slides on a frictionless track from some initial height through a loop-the-loop with radius R = 6.9 m and then along a flat straight section at the height R/2 above the ground. Assume the block never leaves the smooth track at any point on its path and the track is frictionless What is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? At what height above the ground must the block begin from rest to make it around the loop-the-loop? It turns out that engineers who designed the loop-the-loop didn’t really know physics – when they made the ride, the initial height was only as high as the top of the loop-the- loop. To account for this honest mistake, they decided to give the block an initial velocity right at the beginning. How fast do they need to push the block at the beginning (now at a height equal to the top of the loop-the-loop) to get it around the loop-the-loop…
The string in the figure is L = 112 cm long, has a ball attached to one end, and is fixed at its other end. The distance d from the fixed end to a fixed peg at point P is 87 cm. When the initially stationary ball is released with the string horizontal as shown, it will swing along the dashed arc. What is its speed when it reaches (a) its lowest point and (b) its highest point after the string catches on the peg? L
