A projectile is fired at an angle of 28 degrees above the horizontal with an initial velocity of 1800 feet per second from an altitude of 1,000 feet above the level ground.

A) Formulate the vector valued function (in simplified form) for the position of the projectile at any time,t.

B) When and where (in terms of down range distance) does the projectile strike the ground? Be clear and label your results, including units.

C) When does the projectile reach it's maximum height and what is the maximum height? Be clear and label your results including units.

Please explain answers.
