Initial velocity = 18 km/h = 18×5/18 m/sec
= 5 m/sec
[ km/h = 5/18 m/sec ]
final velocity = zero
acceleration = change in velocity/time
= ( final velocity - intial velocity)/time
= ( 0 - 5)/2.5 = -2 m/s²
so, retardation = 2m/s²
= 5 m/sec
[ km/h = 5/18 m/sec ]
final velocity = zero
acceleration = change in velocity/time
= ( final velocity - intial velocity)/time
= ( 0 - 5)/2.5 = -2 m/s²
so, retardation = 2m/s²
