Answer: Whenever important physicists are discussed, Galileo Galilei, Isaac Newton, and Albert Einstein seem get the most attention. However, as you’ve seen, Galileo formulated or refined many of his discoveries and theories based on the findings of others who came before him, including Aristotle

10.6960192763 m/s²
Explanation:
d = Diameter of the ride = 16 ft=
r = Radius = 
t = Time taken = 6 seconds
Velocity is given by
The speed is 2.55348650884 m/s
Acceleration is given by
The acceleration is 2.67400481907 m/s²
When the speed is halved
The acceleration is 10.6960192763 m/s²

Answer:
(C) greater than zero but less than 45° above the horizontal
Explanation:
The range of a projectile is given by R = v²sin2θ/g.
For maximum range, sin2θ = 1 ⇒ 2θ = sin⁻¹(1) = 90°
2θ = 90°
θ = 90°/2 = 45°
So the maximum horizontal distance R is in the range 0 < θ < 45°, if θ is the angle above the horizontal.
