please check acceleration, decleration, max velocity and distance value and confirm it.

HELLO!
 
Maximum velocity that the car can attain is 24 m/s, so v = 24 m/s.
Maximum acceleration a = 1 m/s2
Maximum retardation = 4 m/s2
Distance given = 200m.
 
Car starts from rest and ends by going to rest.
 
Now, time required by the car to start from rest and accelerate to 24 m/s at a rate of 1m/s2  is:
v = u + at
=> 24 = 0 + 1xt
=> t = 24 seconds.
 
Distance covered in this 24 seconds:
S = ut + ½ at2
=> S = 0 + ½ x 1 x 24 x 24
=> S = 288m, which is coming greater than the given value.
 
So, it is proved that there’s something incorrect in the question.
The question, hence, is invalid.
						

							
Is it 22.36 (10/5)
