Part A: Launching a Projectile (1) Position the projectile launcher so that it launches the bal horizontally (2) Record the height of where the ball leaves the launcher (3) Push the bal all the way into the back (3 clicks) making (4) Make a test shot to determine where the ball lands. At this place tape a sheet of white pa (5) Fire the ball 6 different times and record the distance traveled by the ball. check this. If it has moved forward, you must push it back ground. Place the carbon paper on top Do not tape the carbon paper down sure it does not move forward. Please paper to the Height of launcher = 10m Horizontal Distance (m) Average Distance traveled by ball3.40m 3. 295m .333m 3395 m 3.432 m 3.47m smo) 3.504m Part B: Initial Velocity Calculation Calculate the initial velocity of the ball in Part A by filling out the table with the known information and solving the motion equations, 2 2 AVE aL 9 8mls2 3.40 (047 V 7.23 m ls 23mls OX

Explanation / Answer

As the ball projected horizontally, the time of flight remains same as before.

Time of flight is independent of horizontal velocity.

t= 0.47 second

==============

Horizontal range,

X= horizontal speed* time

On doubling the velocity, range also doubles.

X= 2*7.23*0.47= 6.8 m

======

Comment in case any doubt.. good luck
