Question

Part C: Use the result from Part B to evaluate the value of horizontal position of the pumpkin trajectory, xm, at which the slope of y(x) is 0.

Part A
A student club is designing a trebuchet for launching a pumpkin into projectile motion. Based on an analysis of their design, they predict that the trajectory of the launched pumpkin will be parabolic and described by the equation y(x) = ax² + bx where a = −8.0 × 10−³ m¯¹,
b = 1.0 (unitless), x is the horizontal position along the pumpkin trajectory and y is the vertical position along the trajectory. The students decide to continue their analysis to predict at what position the pumpkin will reach its maximum height and the value of the maximum height.
What is the derivative of the vertical position of the pumpkin trajectory with respect to its horizontal position?

2axm+b has its minimum value, which must be determined by obtaining
2axm+b=0
n² +b=0

= axm
2axm + b = ymax, which will be determined in the next step of the analysis
