<h2>The value of r = 
</h2>
Step-by-step explanation:
We have,
U = F(r + B)
To find, the value of r = ?
∴ U = F(r + B)
Dividing both sides by F, we get
⇒ = r + B
⇒ r + B =
⇒ r = - B
⇒ r =
∴ The value of r =
Answer:
The Acceleration of bike after 3 minutes of ride is 14 meter² per minutes
Step-by-step explanation:
Given as :
The displacement of bike is the function of time
i.e s(t) = t³ - 2 t² + 3 meters
The Time of bike acceleration = t = 3 minutes
Let The Acceleration of bike = a meter² per minutes
Now, According to question
∵ <u>Acceleration is define as the rate of change of velocity</u>
i.e acceleration =
or, a =
And
<u>Velocity is define as rate of change of displacement</u>
i.e velocity =
Or, v =
Since here displacement is function of time
So , v =
Or, v =
Or, v = 3 t² - 4 t + 3
So, velocity is the function of time = v = 3 t² - 4 t + 3 meter per minutes
Now, Again
Acceleration = a =
Or, a =
Or, a = 6 t - 4
∴ Acceleration is the function of time = a = 6 t - 4
Now, Acceleration of bike after 3 minutes
So, at t = 3 min
i.e a = 6 t - 4
Or, a = 6 × 3 - 4
Or, a = 18 - 4
∴ a = 14 meter² per minutes
Hence, The Acceleration of bike after 3 minutes of ride is 14 meter² per minutes . Answer
