Question 557790: Driving my car at 100km/hr, I decide to accccelerate-20 km/hr/hr for 30 minutes.what is my final velocity?(convert time to hours
Answer by prateekagrawal(56) (Show Source): You can put this solution on YOUR website!
By the first equation of motion , v = u+at
here, u=100 km/hr
a=20 km/hr/hr
t=30 minute =1/2 hr
hence,
v= 100+20*(1/2)
v= 100+10
v= 110
so, final velocity of car = 110 km/hr . :)
