A car traveling at 26 m/s skids to a stop in 3 seconds. Determine the skidding distance of the car.
Aleksandr [31]

Hello!

Topic: Cinematic

For this we can say:

Initial velocity (u) = 26 m/s

Final velocity (V) = 0 m/s

Time (t) = 3 s

Distance (d) = ¿?

For calculate skidding distance, let's applicate the formula:

\boxed{d = \frac{(u+V)}{2} *t}

Replacing:

d = (\dfrac{26m/s+0m/s}{2})*3s

d =\dfrac{26m/s}{2} * 3s

d = 18m/s * 3s

d = 54\ m

The distance is <u>54 meters (m)</u>

Consider the waves on a vibrating guitar string and the sound waves the guitar produces in the surrounding air. The string waves
tatiyna

Answer:

Frequency is the correct answer.

Explanation:

When a wave go from one medium to another medium then the velocity, wavelength and Amplitude changes. But there is no change on the frequency.

Here, The string and the surroundings air are two medium , from which the wave travels.

So, the wave has same frequency in both medium.

The correct answer is Frequency.
