Question

Megan borrowed eight skateboards from her friends. She rode the skateboards, one at a time, straight down a ramp that had a 30° angle. Four of the skateboards had 48-millimeter wheels and four had 60-millimeter wheels. Megan started each ride from a still position at the top of the ramp. Megan's friend Adele measured the amount of time it took Megan to ride from the top of the ramp to the bottom on each skateboard. Identify the question that Megan and Adele's experiment can best answer.?

Answer 1

Megan and Adele's experiment can best answer the question of how different wheel sizes affect the time it takes for a skateboard to ride down a ramp.

Step-by-step explanation:

When it comes to car speed, wheel size has two major impacts. Larger wheels increase the weight or the load of the vehicle and reduce acceleration. It is important to note that bigger wheels mean you can reach a higher top speed, but the time you take to get that higher speed could be significantly longer.

Larger wheels need more engine power/torque to get moving and smaller wheels accelerate faster, but it doesn't matter. A 29” wheel has more mass at a larger radius from the center of rotation (the hub), and thus has a higher moment of inertia than a smaller wheel and is harder to get moving.

Megan and Adele's experiment can best answer the question of how different wheel sizes affect the time it takes for a skateboard to ride down a ramp. By measuring the time it takes for Megan to ride each skateboard down the ramp, they can compare the results and see if the wheel size has any impact on the speed of the skateboard. They can use the data to analyze the relationship between wheel size and speed and draw conclusions.
