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.
The length and width of the terrace are 15 feet and 6 feet respectively.
The area of the terrace is 90 ft²
The scale of the plan is 2 inches : 6 feet.
Therefore, 2inches represents 6 feet.
According to the drawing;
- length = 5 inches
- width = 2 inches
Therefore,
- length of the terrace = 5 × 6 / 2 = 30 / 2 = 15 feet
- width of the terrace = 2 × 6 / 2 = 12 / 2 = 6 feet
The area can be found as follows:
<h3>Area of a rectangle:</h3>
where
l = length
w = width
Therefore,
area = 15 × 6 = 90 feet²
