Accleration,a=1m|s^2 and distance,s=25m

na2028: u r wrong
somanbijuowbx38: s=37.5

Initial velocity, u=18 km/hr
Final velocity ,V =36 km/hr
Time.t =5 secs
Acceleration ,a=v-u/t
                          =36-18/5
                            =18/5=3.6m/s²
 distance= s
                         =v²-u²=2as
                           36²-18²=2×3.6×s
                           1296-324=7.2s
                            s=972/7.2
                             s =160mts

pbasista406: You r wrong to convert km per hour we need to multiply it by 5 and divide it by 18
na2028: oh yes!!! thanks
na2028: saw it afterwards
