Question

A person observes smoke from a cannon when it was fired. 1.5 seconds later, he hears the bang. If the cannon is 510 m away from the observer, calculate the velocity of the sound in air.​

Answer 1

Answer:

Velocity of the sound in air = 340 m/s.

Explanation:

Given that:

• Distance (d) = 510 m

• Time (t) = 1.5 seconds

To find:

Velocity of the sound in air.

Solution:

We know that,

Velocity = Distance/Time

By substituting the known values, we get

v = 510/1.5 = 340 m/s.

Thus, velocity of the sound in air = 340 m/s.

Answer 2

Given:-

• A person observes smoke from a cannon when it was fired. 1.5 seconds later, he hears the bang. If the cannon is 510 m away from the observer.

To find:-

• Calculate the velocity of the sound in air.

Solution:

Here we use the concept of finding the velocity.

As from given :-

• (d) = 510 m
• (t) = 1.5 seconds

Here,

"d" = Distance covered.

"t" = Time Taken

Applying the formula of velocity,

⇒ $Velocity = Distance/Time$

Putting up the values in the above formula

⇒ velocity = 510/1.5 = 340 m/s.

Therefore, velocity of the sound in air ↠ 340 m/s.
