Launching a Projectile on the Moon
Problem Statement:
An astronaut stationed on the moon decides to launch a linkbot upward to give it a projectile motion. The linkbot starts at y = 0 and follows a parabolic path as it travels. Its vertical position can be described by the following equation: y = -0.5x2 + 8x. Graph the quadratic equation by changing the value of the y-variable in the loop, then find the total distance in the x direction (x-value) traveled by the linkbot once it lands back on the moon (y = 0) if it starts at x = 0. You will graph the equation from x = 0 to the x-value you calculate.
