Answer 2

Answer:ANSWER

s

​  

=ut+(1/2)at

​  

×5×8  

2

 

    =160 m.

The velocity attained in 8 seconds is given by

v=u+at

  =0+5×8=40 m/s.

The distance traveled in the next 4 seconds is  

s  

2

​  

=40×4=160 m.

So, the total distance traveled by the car is s

​  

+s

​  

=160+160=320 m

Explanation: Which means that the the total distance is s1

+s

2

=160+160 = which is equal to 320 metres
