acceleration = final velocity - initial velocity / time
= (90- 120)/15
= -30/15 = -2 km/hr^2
retardation = 2m/hr^2
= (90- 120)/15
= -30/15 = -2 km/hr^2
retardation = 2m/hr^2

a=v-u/t
90km/hr-120km/hr/15
-30km/hr/15
retardation acceleration=-2km/hr
90km/hr-120km/hr/15
-30km/hr/15
retardation acceleration=-2km/hr
