Question

A TRUCK TRAVELLING AT 54 KM/H IS SLOW DOWN TO 36 KM/H IN 10 SEC.FIND THE RETARDATION​

Answer 1

Answer:

Explanation:

Truck initial speed (u) = 54km/HR

Change into m/s = 54×(5/18)

= 15m/s

Truck final speed (v) = 36 km/HR

Change into m/s = 36×(5/18)

= 10m/s

Retardation = (final speed - intial speed)/time

= (10-15)/10

= -5/10

= -0.5m/s^2
