1. 2D motion.

A cannon fires a ball with a velocity at 300 MPS. THe cannon has an angle of inclination of 50 degrees. The surface is flat. 1. What is the time of flight? 2. Where does it land? What is its maximum height? What is the velocity vector of the ball at impact in component notation? 5. What is the velocity vector of the ball at impact in polar notation?

1. t= 2vₒ不inα/g

2. L=vₒ²不in2α/g,

3. h= vₒ²不in²α/2g,

4.v₀⒳= v₀苗osα =300苗os50=192.8 m/s

v₀⒴ =v₀不inα =300不in50=229.8 m/s

v= 192.8品+229.8彬

5. v,α = 300,50ｰ
