The power is equal to energy transferred per unit time.
So, here power will be due to potential energy of the water kept at a certain height. And water is flowing down at the given flow rate.
The flow rate of water is 200kg/s
And the height given is : 15m
So, we calculate the potential energy as: mgh
Where m is the mass,
g is acc due to gravity = 9.8m/s
h is the height
So, potential energy = 200kg*9.8*15
= 29,400 J
Therefore, the maximum power generated is 29400 J/sec = 29400 Watts
Answer: The ball's acceleration is 2.35 m/s2
Explanation: Please see the attachment below
If the sack weighs 210 newtons, then an upward force of 210 newtons
exactly cancels the downward force of gravity, and makes the net vertical
force on the bag zero.
ANY upward force that's greater than 210 newtons makes the net force
act upward on the bag, and causes it to accelerate upward.
