2/5 = .4
.4*100= 40%

Work = (force) x (distance) =
(200 N) x (3.5 m) = <em>700 joules</em>
Answer:
Kinetic energy would increase by a factor of 4 where as momentum would increase by a factor of 2.
Explanation:
Kinetic Energy is given by 0.5*mass*velocity^2. Kinetic Energy is proportional to Velocity^2.
Momentum is given by mass*velocity. Momentum is proportional to Velocity.
If the velocity of an object is doubled, Kinetic energy would increase by a factor of 2^2 i.e 4 times. Momentum would increase by a factor of 2.
This is your perfect answer
It is flexible. Water flow can be adjusted and even conserved according to the need for power. It is safe! Compared with the use of fossil fuels and nuclear energy, hydropower is a much safer system..
