Question

Problem 2: Consider a 2-D projectile motion in the presence of a gravitational field, in the absence of air resistance. Find the equations of motion for this projectile both using Newtonian mechanics and Lagrangian. Are the results of the two methods equivalent? Why?

Step 1

In Newtonian mechanics, we can break down the motion of the projectile into its horizontal and vertical components. Let's assume that the projectile is launched with an initial velocity v0 at an angle θ with respect to the horizontal axis. The horizontal motion Show more…
