Question

a car accelerates uniformly from 18km/h to 36km/h in 5s .calculate acceleration in m/s^2​

Answer 1

Answer: 1 m/s^2

Explanation:  u=18 kmph= 5m/s   v=36 kmph=10 m/s      t= 5 sec

                    According to equation of motion,

                   v=u+at

                  a= v-u / t

                   =10- 5  /  5

                   =5 /5

                   =1 m/s^2
