A car travelling at 60km /h uniformly retards for 10s and reaches a velocity of 45 km/h. Find the retardation |

Answer» HEY there here is your answer initial velocity (U) = 60km/h = 50/3 m/s final velocity (v) = 45km/h = 25/2 m/s time = 10 s retardation or negative ACCELERATION = v-u/t = 25/2 - 50/3 ÷10 =75-100 /60 = -25/60 = -5/12 = 0.416 m/s^2 hope it HELPS |
