2.05 radians/s
Explanation:
This is a simple harmonic motion. The angular frequency of a loaded spring is given by
where 
is the spring constant and 
is the mass on the spring.
Using the known values,
Answer:
I'm learning physics too, mabye we can learn together. by the way, the are 2 very good apps with physics : "khan academy" and "crash course"
There is no connection there that I can think of.
Answer:
3.422 m/s^2
Explanation:
A useful relation is ...
v2^2 -v1^2 = 2ad
(25 m/s)^2 -(3 m/s)^2 = 2a(90 m)
(616 m^2/s^2)/(180 m) = a ≈ 3.422 m/s^2
The acceleration is about 3.422 m/s^2.
