Question

A car accelerates uniformly from 18 km h in 5 sec to36km h calculate acceleration of car

Answer 1

Acceleration of the car will be 1.6 meters per second square

Answer 2

• Acceleration ,a=v-u/t

                                =36-18/5

                        =18/5=3.6m/s²

•  distance= s

                       =v²-u²=2as

                      36²-18²=2×3.6×s

                     1296-324=7.2s

                                    s=972/7.2

                                   s =160m\s
