We know that, Velocity is the rate of displacement covered. Displacement is the shortest path between the Initial and Final point covered by the body. So,
- Velocity = Displacement / Time
And, when it comes to Average velocity, It is the total displacement by total time taken. So, By using this let's solve this question.....
<h2><u>Solution</u><u>:</u></h2>✏️ Refer to the attachment...
Let the body goes to point A that is 7 m East of the Initial point. Then it comes backward because West is opposite to East in perpendicular direction. It covers 1.5 m backwards in the same line to reach B which is the Final point.
So,
- Displacement = Final point - Initial point
⇛ Displacement = 7 m - 1.5 m
⇛ Displacement = 5.5 m
Total time taken,
⇛ 2 hours + 1 hour
⇛ 3 hours
Finding Average displacement,
⇛ Total displacement / Total time taken
⇛ 5.5 m / 3 hours
⇛ 1.83333.... hours
So, the Final answer is,

Answer:
The spring constant is 215.6 N/m.
Explanation:
Given that,
Distance = 39 cm
Compresses length = 29 cm
Mass = 2.2 kg
We need to calculate the distance
Using formula of distance
Put the value into the formula
We need to calculate the spring constant
Using formula of restoring force
Where, F = force
x = distance
Put the value into the formula
Hence, The spring constant is 215.6 N/m.
