A car accelerates uniformly from rest to 23 m/s over a distance of 30 meters. What is the acceleration of the car?
kolezko [41]

Answer:

a= 17.69 m/s^2

Explanation:

Step one:

given data

A car accelerates uniformly from rest to 23 m/s

u= 0m/s

v= 23m/s

distance= 30m

Step two:

We know that

acceleration= velocity/time

also,

velocity= distance/time

23= 30/t

t= 30/23

t= 1.30 seconds

hence

acceleration= 23/1.30

accelaration= 17.69 m/s^2

There are in fact two turbines, and the first one gets power from exhaustion, which is then used to power to turbine in the turbojet that is used to drive the compressor. This is how turbojets commonly work.</span>
