Answer:
the equation for v is v = 250 km/h * [1- e^(-kt) ]
Step-by-step explanation:
since the acceleration "a" is the rate of change of velocity "v" with respect to the time "t", we have
a= dv/dt= k*(250 - v)
thus
dv / (250 - v) = k*dt
if we proceed then to the indefinite integration in both sides
∫dv / (250 - v) = ∫k*dt
- ln (250-v) = k*t +C , where C= constant
if we know that at t=0 , v(t=0)=0 , then
- ln (250-0) = k*0 +C
- ln 250 = C
replacing C in the original equation:
- ln (250-v) = k*t - ln 250
ln [(250-v)/250] = -k*t
v = 250 km/h * [1- e^(-kt) ]

10. A salesperson advertises an increase of 100% in the radius of a new water pipe into a building.
a) The new pipe radius is how many times the size of the old radius?
b) By what factor will the flow rate of water through the pipe increase?
c) If the old pipe carried water at a rate of 10 gallons/second, at what flow rate will the
new pipe carry water?
d) What is the percentage increase in the flow rate of water in the new pipe?
