The lecture Projectile Motion: Example Part 2 by Jared Rovny is from the course Translational Motion.
A projectile launches with an initial speed of V at an angle of θ with the horizontal. What is the formula for its maximum height?
A firefighter aims a water hose upward at an angle of 78.5° with the horizontal and an initial speed of 32 m/s. What is the maximum height of the water stream? (g ≈ 10 m/s²)
An athlete in a high jump competition leaves the ground at an angle of 87° and attains the maximum height of 1.7 m. What is the initial speed of the athlete at the time of jump? Hint: Use the maximum height formula.
A projectile launches with an initial speed of V at an angle of θ with the horizontal. What is its vertical velocity at its highest point of motion?

I 'm nontraditional science major but all of these videos are good description and easiest to get understand.
