Question

The skateboarder in the drawing starts down the left side of the ramp with an initial speed of 5.4 m/s. If nonconservative forces, such as kinetic friction and air resistance, are negligible, what would be the height

ℎ
h of the highest...

Answer 1

To find the height of the highest point the skateboarder in the drawing reaches, we need to use the principle of conservation of mechanical energy.

Step-by-step explanation:

To find the height of the highest point the skateboarder in the drawing reaches, we need to make some assumptions:

1. The skateboarder starts down the ramp with an initial speed of 5.4 m/s.
2. Nonconservative forces, such as kinetic friction and air resistance, are negligible.
3. The skateboarder does not leave the ramp.

Assuming these conditions, we can use the principle of conservation of mechanical energy to solve the problem. At the highest point, the skateboarder's kinetic energy will be zero, and all the initial mechanical energy will be converted to potential energy. We can calculate the height using the formula:

f m g h
where m is the mass of the skateboarder, g is the acceleration due to gravity, and h is the height.Since the question does not provide the mass of the skateboarder or the acceleration due to gravity, we cannot calculate the exact height. However, the process to find the height would be the same.
