Solution :

For `0 le t le 5 v prop t rArr s prop t^(2)` and `a_(1)=` constant `10/5=2 m//s^(2)` <br> for whole interval `s_(1)=` Area under the curve `=1/2 xx5xx10=25 m` <br> For `5 le t le 10, v=10 ms^(-1)rArr a=0` <br> for whole interval `s_(2)=` area under the curve `=5xx10=50 m` <br> For `10 le t le 12` v linearly decreases decreases with time `rArr a_(3)=-10/2=-5 ms^(-2)` <br> for whole interval `s_(3)=` Area under the curve `=1/2xx2xx10=10 m` <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/ALN_PHY_C02_S01_034_S01.png" width="80%">Related Video
