A spring-loaded ball launcher
context
A spring-loaded ball launcher is embedded in the floor. When the ball launcher is triggered, the ball is propelled into the air and then falls to the ground. We are looking for the horizontal distance travelled by the ball.
Information
The pitcher is tilted at a known theta angle.
The spring, whose spring constant is known, is initially compressed (and ei is known).
At its natural length, the end of the spring coincides with the ground.
The mass of the ball is known, but its diameter is neglected.
Modelization
Create a model (a unique equation!) for the horizontal distance the ball travels (in m) from the mouth of the pitching machine to where it hits the ground.
Then test your model with the following values:
Pitch angle of inclination (theta): 22.2 degrees
Spring return constant: 64.1 N/m
Initial spring compression: 19.8 cm
Mass of ball A: 130 g
