Question

A truck travelling at 54 km/h is slow down to 36 km/h in 10 sec. Find the retardation​

Answer 1

Answer:

Hey mate here is your answer....

initial velocity = 54×5/18 = 15m/s

final velocity = 36×5/18 = 10m/s

Acceleration = 10-15/10 = -5/10 = -2m/s²

Retardation = 2m/s²

Hope it helps you....
