Answer: 12 J
Explanation:
Work = force*displacement
Work= 3N*4m= 12 Joule
By bring their legs close to their bodies, they are decreasing the length of the pendulum which help them move more quickly.
A pendulum is nothing but a body suspended from a fixed point so that it can swing back and forth under the influence of gravity.
Here in this case Gibbons are bringing their legs close to their bodies and reducing the length of the pendulum. Since as the length of the pendulum increases the speed of the movement will be reduced. By bringing their legs close to their bodies they are reducing the length and in turn their speed increase and they move quickly.

Answer:
Renewable Energy
Examples of Renewable energy are :
Solar
Tidal
Wind etc.
Explanation:
To solve this problem we could apply the concepts given by the conservation of Energy.
During the launch given in terms of kinetic energy and reaching the maximum point of the object, the potential energy of the body is conserved. However, part of all this energy is lost due to the work done by the friction force due to friction with the air, therefore
The potential and kinetic energy are conserved and are the same PE = KE and this value is equivalent to 100J, therefore
The kinetic energy will ultimately be less than 100J, so the correct answer is C.
