A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle 11° with respect to the horizontal and with an initial speed of 46 m/s. Air resistance is negligible in this situation. Call up the positive y direction, and toward the wall the positive x direction. What is the earliest time when the height of the projectile is half of its maximum value?

    Create a program that plots the trajectory, from the initial height to the ground, of a projectile accelerating both in the horizontal and vertical directions. -Matlab Code PROBLEM 4: In your physics class, projectile motion has two components: constant-velocity motion in the horizontal direction and free-fall motion in the vertical direction. However, in reality, the horizontal motion has acceleration due to air resistance, wind, and other factors. The goal of this problem is to visualize the trajectory of a projectile...
