Given,  

Initial Velocity (u) = 0 m/s  

Final Velocity (v) = 25.9 m/s  

Time (t) = 2.5 sec  

avg. acceleration = ?  

avg. acceleration = v-u/t  

avg = 25.9/2.5 = 10.36 m/s²  

avg = 10.36 m/s²

Answer:

Acceleration, a=10.4\ m/s^2

Explanation:

Given that,

Initial velocity of the ride, u = 0 (at rest)

Final speed of the ride, v = 22.9 m/s

Time taken, t = 2.2 s

Let a is the acceleration of the passengers on this ride. It can be calculated using the formula of the acceleration as :

a=\dfrac{v-u}{t}

a=\dfrac{22.9-0}{2.2}

a=10.4\ m/s^2

So, the time required to bring the car to a stop is 10.4\ m/s^2. Hence, this is the required solution.

igomit [66]

Answer:

T=Lnsin\alpha

Please check the attached

Explanation:

The torque can simply be calculated by multiplying the length of the rod by the perpendicular force n as shown in the attached figure.

Note that sin90=1

T=Lsin\alpha(nsin90)

T=Lsin\alphaxn

T=Lnsin\alpha

Describe a situation when you might travel at a high velocity bit with low acceleration
iren [92.7K]

I am sitting in my seat.
I am listening to my mp3 and reading my book.
My eyes are getting heavy.  They start to close.
I try to stay awake, but it's no use.
I am so warm and comfortable and sleepy,
and I have just finished my dinner.
Finally I can't help it.  Resistance is futile.
I give up, and fall deep asleep.
My head rests back against my soft, comfy seat.

My seat is in row 26 on the airplane I'm flying in
to visit my grandmother on the coast.
We are cruising at 560 miles an hour, bearing 280°,
at flight level 320 .
The temperature outside my window is  -60°F .
