Acar is moving with acceleration 200 m in 50 sec reached to velocity 10 m\sec .what the total distance the car moved in 60 sec.
v=vₒ+at, => vₒ=v-at,
s=vₒt+at²/2= (v-at)t+ at²/2 = vt- at²/2,
a=2(vt-s)/t² =2(10•50-200)/50²=0.24 m/s².
vₒ=v-at=10-0.24•50= - 2 m/s.
s1= vₒt1+at1²/2 = -2•60+0.24•60²/2=312 m.
