At highway speeds, a particular automobile is capable of an acceleration of about 1.6m/s^2. At this rate, how long does it take to accelerate from 80 km/h to 110 km/h?
So like, something along the lines of 110-80= 30km/h, and then do something with the 1.6 m/s?
So how long does it take him to accelerate a velocity of positive 30 km/h, if he accelerates 1.6 meters every second?
How long does it take him to accelerate a velocity of positive 8.34 m/s, if he accelerates 1.6 meters every second?
8.34/1.6 = 5.215 seconds.
Is that right? Or did I go wrong somewhere? Because I'm really having trouble focusing right now.
