The "ringing sound" are actually the soundwaves travelling from the phone to your ears.
Answer:
The value is
Explanation:
Generally the velocity attained by the sled after t = 3.10 s is mathematically evaluated using the kinematic equation as follows
Here u = 0 \ m/s
a = 13.5
So
=>
The is distance it covers at this time is
=>
=>
Now when sled stops its the final velocity is while the initial velocity will be the velocity after its acceleration i.e
So
Here , the negative sign shows that it is deceleration
So
=>

<h3>
Answer:</h3>
60 m
<h3>
Explanation:</h3>
<u>Concept Used:</u>
We know that the area under a velocity-time graph represents the Displacement of the body
<u>Displacement in the Last 6 seconds:</u>
To find the Displacement in the last 6 seconds, we will find the area under the graph between x = 4 and x = 10
We can see that the shape formed is a rectangle also shown in the given graph. So, the area of the rectangle is the Displacement of the car in the last 6 seconds
<u>Area of the Rectangle:</u>
From the graph, we know that the rectangle is 10 (m/s) tall and 6 (s) wide
Area of Rectangle= length*Breadth
replacing the values
Area = 10 (m/s) * 6 (s)
Area = 60 m
Hence, the car travelled 60 m in the last 6 seconds of the graph
