Direction of resultant force of ball on a track
** Please see the attached file for the complete problem description **
1. After an initial impulse, a ball moves along a track as shown and then moves through the air, following the path shown in the diagram.
(please see the attached file for the diagram)
Copy the diagram and draw arrows to indicate the direction of the resultant force at each position. Ignore air resistance.
3. Briefly describe an experiment to find the coefficient of friction between brick and tile. You may assume access to a tile slab, a number of bricks and basic scientific equipment, such as a pulley, weighing machine, etc.
