i get it but i wonder can i do it with find t when v=0? because your method seem not suitable for finding distance between t and t1(where t and t1 are the time when s=0) can you please point out my mistake in the following equation? |s(5)-s(0)|+|s(10)-s(5)| = 7.5+32.5=40 thanks a lot:)

thanks i got the ans but i wonder why we have to know what time the displacement is zero??i can't get it~.~

yes i use|s(5)-s(0)|+|s(10)-s(5)| = 7.5+32.5=40but the ans is 40 instead of 32.5

1. Homework Statement the following is a equation to find the displacement of a particle. I've found it is instantaneous at rest at t=5. now need to find the distance traveled between 0 to 10s. i found distance traveling between 0 to 5 s is 7.5 and between 5s to 10s is 32.5...so how come...
