Accelerates 82218

The object has a speed of 25m/s and accelerates 5.0m/s2 for 250 meters. What is the final velocity?

Correct answer:

v2 =  55.9017 m/s

Step-by-step explanation:

v1=25 m/s a=5.0 m/s2 s=250 m  s=v1 t+0.5 a t2  250=25 t+0.5 5 t2 2.5t225t+250=0 2.5t2+25t250=0  a=2.5;b=25;c=250 D=b24ac=25242.5(250)=3125 D>0  t1,2=2ab±D=525±3125=525±255 t1,2=5±11.18034 t1=6.180339887 t2=16.180339887  t=t1=6.18036.1803 s  v2=v1+a t=25+5 6.1803=25 555.9017 m/s   Verifying Solution:   s2=v1 t+21 a t2=25 6.1803+21 5 6.18032=250 m
