A sports car accelerates from rest to 95 km/h (Kilometers per hour) in 4.0 seconds.
The whole thing with converting the acceleration into m/s^2 (meters per second squared) is really screwing me up. Could you please answer this step by step including how you converted it?

First, let's do the conversion for the velocity. 1 km = 1000 m, so 95 kilometers/hour is the same as 95,000 meters/hour.
Now, one hour = 3600 seconds. 95,000 m/hour*(1 hour / 3600 seconds) = 95,000/3600 m/second = 26.3889 m/s
Then, acceleration is just a = v/t = 26.3889/4 = 6.5972 meters/second^2
Now, one hour = 3600 seconds. 95,000 m/hour*(1 hour / 3600 seconds) = 95,000/3600 m/second = 26.3889 m/s
Then, acceleration is just a = v/t = 26.3889/4 = 6.5972 meters/second^2

95 km/h = 95000 m/h = 95000*60 m/min = 95000*3600 m/s = 342000000 m/s
a=s/t = 342000000/4 = 85500000 m/s^2 = 8.55*10^7 m/s^2
Hope it helped :D
