Problem 4: (use energy methods) When s = 0, the spring on the firing mechanism is unstretched. If the spring is pulled back to s
= 100mm and released. The mass of the ball is 0.3kg. Determine: 1. The speed of the ball as it leaves the spring and is about to start moving on the circular track. 2. The maximum angle θ the ball will travel without loosing contact with the circular track. Assume all contact surfaces to be s

Answer:
0.08024 W/m²
Explanation:
P = Power
= Distance = 15 m
= Intensity at 15 m = 0.26 W/m²
= Distance = 27 m
= Intensity at 27 m
Sound intensity is given by
So, we have the relation
The sound intensity at the given distance is 0.08024 W/m²
