Question

A car travelling at a uniform speed of 60km/h retards in 10s and reaches a velocity of 45km/h.Find its retardation​

Answer 1

(u)initial velocity=60 km/hr

(v)final velocity=45 km/hr

acceleration=(v-u) /t

acceleration=-15/10

acceleration=-1.5m/s²

therefore,

retardation =1.5 m/s²

hope it helps
