To fill a child's inflatable wading pool, you use a garden hose with a radius of 3 cm. Water flows from this hose with a speed of 1 m/s. How long will it take to fill the pool to a depth of 10 cm if it is circular and has a radius of 2.9 m

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
