  1. Cannonball People!

  2. Created Values • Vx= 30 m/s • Vyi= 10 m/s • a= -9.81 m/s²

  3. Solving for time • Vyf=-Vyi • Vyf=Vyi+at • (-10 m/s)= (10 m/s) + (-9.81m/s²) t • (-20m/s)/(-9.81m/s²)=t 2.0387s=t

  4. Solving for Change in x • Vx= Δx/t • 30 m/s = Δx/2.0387s • (30m/s)(2.0387s)=Δx Δx= 61.161m

  5. Solve for Change in y • ymax= Vyi(t/2) + ½ a (t/2)² • ymax=(10m/s)(2.0387s/2)+½(-9.81m/s²)(2.0387s/2)² • ymax=10.1935m+(-4.9999) ymax= 5.1936m

  6. Vertex of the Hoop • ( ½ Δx, ymax) • (½ 61.161m, 5.1936) Vertex= (30.5805,5.1936)

  7. Diagram! Top: 5.19m high 30.58m over 61.16m from canon

  8. Summary • Vx= 30 m/s • Vyi= 10 m/s • a= -9.81 m/s² • 2.0387s=t • Δx= 61.161m • ymax= 5.1936m • Vertex= (30.5805,5.1936)
