Question

A car travelling at 67 km/h slows down to 33 km/h in 15 seconds find the retardation.​

Answer 1

Answer:

initial velocity u =67km/hr=335/18 m/s

final velocity v=33km/hr =165/18 m/s

time t =15 s

a =v-u /t

a=(335-165)/18x 15

a=170 /18 x15

a=17 /27

Answer 2

Step-by-step explanation:

a=170/18×15

a=17/27
