How long will it take a car to go from a complete stop to 44 km/hr if they are accelerating at 5km/hr2?
\(\ddot x=5\\ \dot x = 5t\\ when\\ \dot x = 44\\ 5t=44\\ t=8.8 \;hours \)
I have not bothered with constants because when t=0, x=0 and v=0
vf = at
44 = (5) t
44/5 = t = 8.8 hr
8.8 hours...........
