Answer:
Correct answer: A.) V = - 16.6 m/s down
Explanation:
Given:
V₀ = 3 m/s initial velocity
t = 2 seconds
g = 9.8 m/s²
V(t) = V(2) = ?
The movement described is a vertical upward shot
For velocity at any time is valid the next formula
V = V₀ - g · t
V = 3 - (9.8 · 2) = 3 - 19.6 = - 16.6 m/s down
Under condition that it has a enough drop height with respect to the ejection point.

Answer:
N = 2500
Explanation:
By definition, the sampling frequency (fs) is:
<em>where N: is the number of samples and T: is the time</em>
Hence, the number of samples at the sampling frequency, 500 Hz, to get 5 seconds of data is:
