Vf = Vi + at
Vf = 0 + 5.4•28
= 151.2m/s..

Speed is equal to distance divided by time
Answer:
The value is 
Explanation:
From the question we are told that
The initial speed is
at a distance of 
The final speed is
at a distance of 
Generally from the kinematic equation we have that

=> 
=> 
=> 
The negative sign shows that it is decelerating
