A cycle is travelling at the speed of 50 km/h after applying brakes body accelerates uniformly and take 10 s to stop and another cycle travelling at the speed of 40 km/h after applying brakes the cycle stop in 20 s . find who travel farthest after applying brakes and also plot the speed versus time between two cycles in a graph .

let  the 1st cycle A ,
    time taken ( let it be  t1 ) = 10 s 
    speed ( let it be v1 )  = 50 km/h = 50 * 1000/3600 m/s
      distance ( let it be d1 ) = ?
 let the 2nd cycle B ,
      time taken ( let it be t2 ) = 20 s 
      speed ( let it be v2 ) = 40 km/h = 40 * 1000/3600 m/s
      distance ( let it be d2 ) =  ?

d1 = speed * time 
    = 50 * 1000*10/3600 
    = 138.88 m
d2 = speed * time 
    = 40 * 1000* 20 /3600 
     = 222.22 m 
.·. cycle B is go farther .
