The law of conservation of energy. The energy due to work performed on the skateboarder is converted into kinetic energy such that:
Work=Kinetic Energy
So 380=(1/2)(35)(7-Vo). I don’t have a calculator so..
Assumptions we made:
No energy loss, all work went into the energy of motion of the skateboarder. In the real world, this is not possible because some of the energy can be loss through friction of the skateboarder to the ground etc.
In oder to count the percentage you have to divide the number of instances over the number of possible instances and multiply by 100% (100 % is also 1).
4/50*100%= 2/25*100%=2*4%=8 %.
So the answer is 8 %.
Answer: x = 8, -4
