Question

A car accelerates uniformly from 18 km h to 36 km h in 10 seconds calculate its acceleration in km/h

Answer 1

Answer:

18km×36km

=648km

=648×10

=6480km

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
