A water tank is used to collect off of roofs to be used as irrigation for a home garden. The tank is 5.1 m tall and has a faucet at the bottom to release the water. What is the speed of the water as it leaves the faucet?
Assume that the tank is large enough that the velocity of the water at the top is zero. The acceleration of
gravity is 9.81 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

magnets not strong enough
