Question

Raul wants to investigate how the angle of a ramp affects the speed of an object rolling down the ramp. Which investigation should he perform?

Option 1: Observe different bicyclists riding down hills of varying steepness.
Option 2: Record the time it takes one bicyclist to ride down hills of varying steepness.
Option 3: Perform an experiment in a lab in which the angle of the ramp is controlled, and the speed of a rolling cart is measured.
Option 4: Observe video of various objects rolling down hills and estimate the angle of the hill and the speed of the object.

Answer 1

Raul should perform an experiment in a lab to investigate how the angle of a ramp affects the speed of an object rolling down the ramp.

Step-by-step explanation:

To investigate how the angle of a ramp affects the speed of an object rolling down the ramp, Raul should perform Option 3: Perform an experiment in a lab in which the angle of the ramp is controlled, and the speed of a rolling cart is measured.

In this experiment, Raul can vary the angle of the ramp and measure the speed of a rolling cart using a stopwatch or a motion sensor. By controlling the angle and collecting data, he can determine the relationship between the angle of the ramp and the speed of the object.

Performing this experiment in a controlled environment like a lab allows for accurate measurements and eliminates external factors that could affect the results.
