Question

A car moving with a certain velocity comes to a halt , if the retardation was 5m/s square, find the initial velocity of the car.(ans=25m/s)

Answer 1

Answer:

v=0 ,a =-5m/s^2

v=u+at

0= u -5t

-u=-5t

u=5t

in ur question ther is no t but as I have referred in ur answer as 25 then t=5

u=5×5

u=25m/s
