10/22: TEST ON 2D MOTION
Important things to remember when solving:
- Time is a scalar quantity and can be used in vertical and horizontal motions.
- Horizontal information can only be used in horizontal formulas. Vertical information can only be used in vertical formulas.
- Gravity only effects the projectile in the vertical direction.
- Velocity is constant in the horizontal direction.
- For a horizontal projectile –an object simply rolling off a grade.
- The initial vertical velocity is 0 m/s.
- If you have a vertical distance, you can find time using dy= ½ gt2
- For a projectile shot at an angle –
- Use SOHCAHTOA to separate the given information into x and y components. Then use these new numbers you find in your horizontal and vertical formulas.
- If asking for vertical distance (dy) and given time for the entire time of the trip, divide time by 2 to solve.
