  Fusion has to do with the release of energy which could be use to power other reactions Functional energy just as the name says refers to energy produced due to mechanical actions which could be used to run a plant or any energy needing area (provide energy) .

  Fusion produces much more energy as compared to fission, about 3 or 4 times more There are few radioactive waste particles produced during a fusion reaction as compared to a fission reaction. Hence it is more environmentally friendly. b) Functional energy is energy obtained from the step by step conversion of a primary fuel such as in a power station or a refinery which is readily usable by the end user.

  Good Kemba Daniel, you got the right answers for the velocity. Try to present your work in a clear and concise manner for easy understanding and use a diagram every time

To determine the velocity of a pellet, a piece of plastine 50g is balanced at the edge of a table such that it fails to fall off. A pellet of mass 10g is fired horizontally into the plastine and remains embedded in it. As a result the plastine reaches the floorat a horizontal distance of 0.25.

1.whats the horizontal velocity of the plastine given that the table surface is 0.6m high

2.what's the velocity of the pellet just before it hits the plastine.

3.whats the Velocity of plastine just before impact with the floor at a horizontal distance of 0.25

4.describe energy changes of the plastine.
