The only tricky algebra in kinematics is if you need to solve equation 1 when v 0 is not equal to zero. -b b²-4ac 2a. X -b b² - 4ac2a.
Remember when inserting the numbers to insert them with parenthesis.
Using the quadratic equation to solve for v we get v equals 5 meters per second and -34 meters per second. X -b b² - 4ac2a. You can calculate the discriminant b2 - 4ac first. Here are the main equations you can use to analyze situations with constant acceleration.
