Answer:
hello the answer is 47m/s
Answer:
gs = 0.6 m/s^2
Explanation:
Given data:
velocity = 12 m/s
height s = 12t -(1/2) g_s t^2
Given velocity is the derivatives of height



when velocity tend to 0 , maximum height is reached



at t = 20 sec ball reached the max height, so

The answer is A. Hope this helps I tried my best!
Psychology is considered a science because it utilizes scientific methodology for devising treatments and measuring outcomes.
The mass of the object is 0.0076 kg
Explanation:
The frequency of a mass-spring system (simple harmonic motion) is given by

where
f is the frequency
k is the spring constant
m is the mass
For the mass-spring system in this problem, we know:
k = 30 N/m is the spring constant
f = 10 Hz is the frequency
Solving the equation for m, we find the mass:
