Application: Object in Motion
Apply Grade 9 math skills to real-world problems in Application: Object in Motion. Connect algebra concepts to consumer math, motion, and practical scenarios.
Key Concepts
Property The height of an object tossed upwards can be modeled by $ 4.9t^2 + vt + s = 0$, where $t$ is time, $v$ is initial velocity, and $s$ is initial height. Explanation This formula is a real world quadratic equation that models the path of a tossed object. It helps predict when something will hit the ground. Since time moves forward, we only use the positive solution from the quadratic formula. A negative answer for time doesn't make sense, so we discard it as an impossible solution. Examples A ball is tossed from a height of 60 meters with a velocity of 8 m/s. Use $ 4.9t^2 + 8t + 60 = 0$ to find when it lands. The positive solution is $t \approx 4.41$ seconds. A ball is tossed from a 50 meter cliff with a velocity of 6 m/s. Use $ 4.9t^2 + 6t + 50 = 0$ to find when it lands. The positive solution is $t \approx 3.82$ seconds.
