Explanation:
Plato/Edmentum
speed of 5,000 meters per second?
Answer:
Period T = 0.1 second
Explanation:
Given that the
wavelength = 500 meters
speed V = 5000 meters per second
The wave speed is the ratio of wavelength to period of the wave. That is,
V = λ/T
Where
V = wave speed (m/s)
λ = wavelength (m).
T = period (s)
Using the formula above gives
5000 = 500/T
Make T the subject of formula
T = 500/5000
T = 0.1 s
Answer:
9.23 m/s
Explanation:
Let, the initial velocity be ux.
The horizontal velocity remans the same. So, time required, t = 25/ux
For vertical component, we know,
h = uy*t + (1/2)*g*t^2 [ g is positive because ball is falling downward ]
Putting in the values, we get,
36 = 0*(25/ux) + 1/2 * 9.81 * (25/u)^2
36 = 3065.625/u^2
u^2 = 85.15625
u = 9.23
