EXPERIMENT 1: PROJECTILE MOTION

EQUIPMENT NEEDED:
--Projectile Launcher and plastic ball.
--Plumb bob.
--Meter stick.
--Carbon paper.
--White paper.
PURPOSE:
The purpose of this experimentis to predict and verify the range of launched at angle.
The initial velocity of the ball is determined by shooting it horizontally and measuring the range and the height of the launcher.
THEORY
Topredict where a ball will land on the floor when it is shot off a table at some angle above the horizontal, it is necessary to first determine the initial speed (muzzle velocity) of the ball. Thiscan be determined by shooting the ball horizontally off the table and measuring the vertical and horizontal distances through which the ball travels. Then the initial velocity can be used to calculatewhere the ball will land when the ball is shot at an angle.
HORIZONTAL INITIAL VELOCITY:
For a ball shot horizontally off a table with an initial aped, Vₒ, the horizontal distance travelled by theball is given by x=Vₒt, where t is the time the ball is in the air. Air friction is assumed to be negligible.
The vertical distance the ball drops in time t is given by y=12gt2
The initial velocity ofthe ball can be determined by measuring x and y. the time of flight of the ball can be found using.
t=2yg

And then initial velocity can be found using Vₒ=xt.
INITIAL VELOCITY AT AN ANGLE:
Topredict the range, x of a ball shot off with an initial velocity at an angle, above the horizontal, first predict the time of flight using the equation for the vertical motion:
y=yₒ+vₒsinѳt-12gt2Where yₒ is the initial height of the ball and y is the position of the ball when it hits the floor. Then use x=(Vₒcosѳ)t to find the range.
SETUP
1) Clamp the projectile launcher to a sturdytable near one end of the table.
2) Adjust the angle of the projectile launcher to zero degrees so the ball will be shot off horizontally.
