Explore teaching strategies to help students succeed on the ACT® math test using TI technology.
Students use precompiled data to calculate the angle of a ramp from the displacement of a ball rolling on the ramp.
Students use a precompiled data set to determine the angle of a ramp. The data set contains position vs. time data for a ball rolling up and down a ramp.
Students fit a parabola to the position vs. time graph. They use the characteristics of the data set (i.e., the vertex of the data points) to predict the equation that best fits the data.
Finally, students use the best-fit equation and the kinematic equations to calculate the angle of the ramp.
