v = 40 km /hr = 11.11 m/s
t = 10 sec.
u =0
retardation = u - v/t = -11.11 / 10 = - 1.11 m/s...............

Hey there !!
Initial velocity = u = 40 km /hr = 40 x 5/18 = 11.11 m /s
Final velocity = v = 0 m/s
Time = t = 2 sec
a = retardation
Equation of motion :
v = u + at
0 = 11.11 + 10a
10a = -11.11
a = -11.11 / 10
a = - 1.111 m/s²
Initial velocity = u = 40 km /hr = 40 x 5/18 = 11.11 m /s
Final velocity = v = 0 m/s
Time = t = 2 sec
a = retardation
Equation of motion :
v = u + at
0 = 11.11 + 10a
10a = -11.11
a = -11.11 / 10
a = - 1.111 m/s²
