4. Theoretical Background:
<projectile motion> (1) The horizontal motion
x-x0=(v0cosθ0)t
(2) The vertical motiom
y-y0=(v0sinθ0)^2-1/2 gt^2
∴vy^2-(v0sin θ0)^2 = -2g(y-y0)
(3) The equation of the path
y=(tanθ0)x-gx^2/2(v0 cosθ0)^2
(4) The horizontal Range
R=(v0 cos θ0)t
0=(v0 sin θ)t-1/2 gt^2
∴R=2v0/g sin θ0 cos θ0
=v0^2/g sin 2θ
5. Method & Resort & Analysis
1) Determining the Initial Velocity of the Ball
① Put the plastic ball into the projectile launcher and cock it to the long range position. Launch one ball to locate where the ball hits the floor. At this position, tape a piece of white paper to the floor. Place a piece of carbon paper(carbon - side down) on top of this paper and tape it down. When the ball hits the floor, it will leave a mark on the white paper.
② Fire about ten shots.
③ Measure the vertical distance from the bottom of the ball as it leaves the barrel (this position is marked on the side of the barrel) to the floor.
