a particle of mass m moving in the x direction at constant acceleration a . During a certain interval of time, the particle accelerates from v_initial to vfinal , undergoing displacement s given by s=x_final-x_initial.(adsbygoogle = window.adsbygoogle || []).push({});

Express the acceleration in terms of v_initial, v_final, and s:

that was easy.. i got

a=(v_final-v_initial)/(s/((v_initial+v_final)/2))

since F=ma

W=F*s

the question isGive an expression for the work in terms of m, v_initial, v_final?

and i cant seem to eliminate the 's' because i end up getting

W=m*a(see above) *s and i cant get eliminate it? any ideas?
