Question

The Julian problem not the one on top.

### Physics Problems 1. **Roller Coaster Problem**: - A roller coaster car goes 14.73 m/s at the top of a vertical circular loop of 20m radius. There is no friction. - Question: What would the magnitude of the normal force on the car be when moving straight down (20m from the bottom) in Newtons (N)? 2. **Projectile Motion Problem**: - Julian throws 5-gram pebbles at Danny's window. The pebbles hit the window at 2.3 m/s. - Question: How fast (in m/s) does Julian throw the pebbles if he throws them from 3.0m below the window? ### Diagram Explanation - The image contains a red squiggly line, which could represent a section of a path or trajectory. The line itself is a simple curve without numerical data or further context.
