v-u/t =a /d
54km/h *5/18=15 m/s =u
v=0 m/s
t=5sec
0-15/5=-3m/s acceleration
retardation is 3m/s
54km/h *5/18=15 m/s =u
v=0 m/s
t=5sec
0-15/5=-3m/s acceleration
retardation is 3m/s

hey mate ur ans
initial velocity - 54 km/ h »» 15 m/s
final velocity - 0 m/s
time - 5 sec
by applying formula
«v=u+at »
0=15+a*5
0=15+5a
0-15=5a
-15=5a
a=-15/5
a=-3m/s2
THEREFORE retardation is of 3 m/s2
