Amy purchased a brand-new mountain bike, which she's riding through
the winding trails. the bike's displacement is given by
s(t) = t3 - 2t2 + 3. what is the bike's acceleration after three minutes?

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

∵ Acceleration is define as the rate of change of velocity

i.e acceleration =

or, a =  

And

Velocity is define as rate of change of displacement

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

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.
