purpose
The purpose of the Projectile Bulls-eye task was to calculate the range of ball travelling in projectile motion so that it hits the target found.

procedure
- Measure all the quantitative data such as height of ramp, diameter of the ball and the mass of the ball
- Derive the equation for the horizontal range of the ball after it goes into the projectile motion
- Plug in the values to find the horizontal range
- Release the ball bearing and measure your target to check if you have hit the bull's eye

Mass of the ball - 0.02837 g
Height of the ramp - 0.31 m
Diameter of the ball - 0.02 m
Time the ball took to travel the circumference - 0.010372
Height of the ramp - 0.31 m
Diameter of the ball - 0.02 m
Time the ball took to travel the circumference - 0.010372
calculations
Analysis
We were not fully successful in throwing the ball in the bull's eye. This might be due to the calculations that were not rounded precisely. Also, air resistance might have played some role in the ball at projectile motion. For the future, we would like to improve calculating precisely and round up calculations to correct significant digits.
