Motion in a Plane

 

I.          2-Dimensional Motion and Trajectories

 

What kinds of objects have 2 dimensional motion?

 

 A)  Objects moving along earth’s surface (projectiles)

 

        1. Projectile fired horizontally

 

 


                       

What you need to know before solving this type of problem:

 

 

 

 

B) Projectile fired horizontally - Solving Word Problems

Use all the same motion equations you used before 

Ex) A baseball is thrown horizontally from a grandstand 20 m above ground at speed of 10 m/s.
  (a) How long will the ball remain in flight before reaching ground?

 

 

 

 

 

 

 

(b) What is the projectile's maximum range before it hits ground?

 

 

 

 

3.   Projectile fired at an angle
