Question

a car is travelling the north with the speed of 54km/h .After 5 sec it starts moving towards west with the same speed.calculate the acceleration produced in the car

Answer 1

Hi ,

The total distance covered = 54 + 54 = 108 Km
The final displacement = 542 Km

Average speed = Distance / time = 108 / 2 = 54 Km/h
Average velocity = Dispalcement / time = 542 /2 = 272 Km/h

thanks
