Yes,and because not everyone can wink and often that someone can only wink with one eye only
Given that,
The acceleration of gravity is -9.8 m/s²
Initial velocity, u = 39.2 m/s
Time, t = 2 s
To find,
The final velocity of the shot.
Solution,
Let v is the final velocity of sling shot. Using first equation of motion to find it.
v = u +at
Here, a = -g
v = u-gt
v = (39.2)-(9.8)(2)
v = 19.6 m/s
So, its velocity after 2 seconds is 19.6 m/s.
Is this like a zoom or something like that
Answer:
The frequency of a wave is 35 Hz.
Explanation:
Speed of a wave is 140 m/s
Wavelength of a wave is 4 m
It is required to find the frequency. The relation between frequency, speed and the wavelength of a wave is given by :
f is frequency
So, the frequency of a wave is 35 Hz.
