Question

a car accelerates uniformly from 18 km h-1 to 36 km h-1 in 5 second calculate the acceleration and the distance covered by the car in that time

Answer 1

......................

Answer 2

Initial Velocity u = 18km/h = 18km/h * 5/18 = 5m/s

Final Velocity v  = 36km/h = 36km/h * 5/18 = 10m/s

• Acceleration = v-u /t

                    = (10m/s - 5m/s) / 5

                    = 5m/s / 5

                    = 1m/s^2
