{14 {m \over s^2}-26m \over 2}= {2 a \over 2} {14 {m \over s^2}-26m \over 2}= a {-12 \over 2} = a -6 = a it's wrong, right?:frown:

sorry if I'm being slow here. so should it be like this 14 m/s2= 0+2a(26 m) ?

now what?:frown:

hmm..so the v_i= 0 and the v_f= 14m/s right?:confused:

v_i= 14 m/s i don't know the v_f. :frown:

just the ones you gave. i tried the first one. but i don't think it's right. v2f= 14m/s2+2(9.8m/s) (26 m) :confused::cry:

sorry. i tried but no. could you please walk me through it. :(

oh now i get it. :smile: i feel really stupid.

i don't get it. why is there an x?

no not really. we haven't discussed this in class yet. the teacher sort of just threw it at us.

well the only equation here related to acceleration is a=v-vo/delta t

umm.. acceleration is equal to displacement over time squared.

acceleration problem (HELP!:(() Homework Statement A vehicle accelerates to 14 m/s after being stopped at a red light. The vehicle covers 26 m to reach its final velocity. How fast was it accelerating? HOW DO I EVEN SOLVE THIS? WHAT EQUATION AM I GONNA USE?! PLEASE HELP.:(
